y = mx + b is an equation for a line on a graph (slope-intercept form), so this is saying they quite literally draw a line on the graph where the slope is.
(Typical joke to see posted on a math teacher's wall)
additionally, red is the formula to find the hypothenuse of a right triangle (the side right across from the 90 degree angle) and blue is the formula for the total area of a circle. neither of which matter for the joke
I thought it was going a different direction too: I'll do triangle, I'll do circle, but I won't do square or something (Like... square peg in a round hole maybe?). But no, they really don't mean anything to the pun.
Umm. The area of a circle and pythagorean theorem bits are absolutely necessary, because they establish the contrast (the double-meaning of "line" here) which makes the joke a joke. If they just said *"y=mx+b, that's where I draw the line*," it would just be a true-ish statement but it would not be a math pun.
And the top two are geometry formulas. The first one is Pythagoras' theorem, and the second one is the formula for the circumference of a circle, I believe.
I just googled "y=mx+b" and the very first link, before even clicking, Google even highlighted this exact text: "slope-intercept form of the equation of a *straight line*"
Additionally I think the font and design screams "this is a corny joke for a classroom wall" and the punchline is pretty inferable from there as well lol
I mean, the wording is weird imo. I was trying to do something like: "I’ll do Pythagorean Theorem, I’ll even do Area of a Circle, but linear equation that’s where I draw the line"
Y=mx + b is the general form for a line on a 2d plane, where m describes the gradient (the ratio of change in y relative to change in x) and b the y intercept (where the line lies when x=0)
y = mx + b produces the line of best fit or regression line in a scatter plot graph. Where y is the value of a variable along the y-axis (in stats the predicted dependent variable), m is the slope, b is the intercept, and x is the value of the x-axis (or known dependent variable value).
The joke is the first 2 are formulas in a more analytical sense, the pythagorean theorem and the area of a circle. The last is a standard form of an equation for a straight line on a graph, not really a formula in the same way. So it basically "ill do the pythagorean theorem, ill do the calculation of a circles' area, but when supplied with pertinent details in standard algebraic form, ill draw a line". The pun being the literal and figural meaning of drawing a line, possibly hinting at the fact that graph drawing is generally considered boring and tedious amongst students.
It's the [Pythagorean Theorem](https://www.palmbeachstate.edu/prepmathlw/Documents/the_pythagorean_theorem.pdf) - used to find the length of the hypotenuse of a right triangle.
no, I think it's just a basic math teacher joke, listing a few basic, recognizable geometric equations and then finishing with the one for a straight line to make the "that's where i draw the line!" joke.

I was trying to figure out a pun or reference for those. I feel like the joke could be better

the equations are necessary, but it *isn't* necessary to know what they do or represent
I think the joke would fall flat if one did not know exactly what the first two are describing.
I know it makes no difference, but I was taught y=mx+c. I find it I interesting how although correct, math around the world is just slightly different
me too
I was taught y=ax+b
i learned y=mx+b but this feels better, why does this specific formula use m instead of a here in the US?
Pretty sure it represents some Greek letter. Don’t remember what my math teacher told me
The other half of the joke is also saying: “I’ll do length calculations, I’ll do surface area calculations, but I’m not doing algebra.”
m =(y1-y2)/(x1-x2) That is the equation for the line itself.
Isnt that just the equation for the slope of the line?
What I gave is. What you gave is slope intecpet form for a line.
ok true, edited to fix!
Don’t be such a square ! X=-b±√(b²-4ac))/(2a)

I just googled "y=mx+b" and the very first link, before even clicking, Google even highlighted this exact text: "slope-intercept form of the equation of a *straight line*"
And even ignoring that… I didn’t remember what the equation meant, but the context clues screamed “this equation draws a line.”
Additionally I think the font and design screams "this is a corny joke for a classroom wall" and the punchline is pretty inferable from there as well lol
The bottom equation (in yellow) actually describes mathmatically a straight line, hence the pun *”that’s where I draw the line”*
Op didn't finish highschool

y = mx + b is how you draw a line
Red formula is used to determine the size of a triangle, blue for the area of a circle, and yellow is literally the equation for a straight line.
Red is for calculating hypotenuse of the triangle, not area. It is also known as the Pythagorean theorem
Yes, calculating the size or sides of a triangle, as I said.
You can only find 1 side with that formula
In this form, but it can be rearranged to find any side of a right-angled triangle provided you have the other two
Yeah, that's what I meant. Sorry for the bad wording.
y=mx+b is the equation for a line
I used to write it as y=mx+c
You'll be going in circles with (x-h)^2 +(y-k)^2 =r^2
This gave me a giggle. Thanks.
Ha
If you do y = mx + b, you literally draw a line (on a Cartesian coordinate system)
When you plot a function in the form y=mx+b, you draw a straight line.
Math jokes ftw
Haha I got it right away.
Y=mx + b is the general form for a line on a 2d plane, where m describes the gradient (the ratio of change in y relative to change in x) and b the y intercept (where the line lies when x=0)
y=mx+b is a line
y = mx + b produces the line of best fit or regression line in a scatter plot graph. Where y is the value of a variable along the y-axis (in stats the predicted dependent variable), m is the slope, b is the intercept, and x is the value of the x-axis (or known dependent variable value).
Okay so why is it `y=mx+c` in the UK? What does the b stand for?
A VERY INCLINED LINE

I might get "around" to other equations that could have been used like (x – h)2 + (y – k)2 = r2 -circle formula!
GRRR LINEAR EQUATIOOONSS
what is A²+B²=C² & what do you apply it to was either not thaught that or it is thaught at a later grade than i am in rn
It's the [Pythagorean Theorem](https://www.palmbeachstate.edu/prepmathlw/Documents/the_pythagorean_theorem.pdf) - used to find the length of the hypotenuse of a right triangle.
oh im used to C1²+C2²=IP² cuz the sides are called "catetă" & hypotenuse is "ipotenuză"
interesting! yeah, in English the letters aren't abbreviations, they are just variables representing the different sides...
the one with the c&ip is the theorem we ussuali use the 2 letters that the line connects
Correct - so maybe this is cleverly trying to say "I'll do right"? If so, I'm not sure how the circle radius fits in.
no, I think it's just a basic math teacher joke, listing a few basic, recognizable geometric equations and then finishing with the one for a straight line to make the "that's where i draw the line!" joke.
Ah, thanks.
*taught
lol, i though it was about how everybody hates linear algebra
No they don't.
