I have a big test tomorrow and am going though my notes and some sample problems from homework. One of the questions is y=3x-41 and I need to find the x and y intercept. I know how to find the x, but forgot how to solve to get the y. Can anyone help? 10/10 for answers!

its been a while but if you can find the x intercept dont you just plug it into the equation and you get y?

To find the x intercept, make y=0. To find the y intercept, make x=0.

Lol. its easy. the y intercept is where x=0. so plug in 0 where x is and solve for y.

y=mx+b

m=slope

b=y intercept

y intercept is -41

It's very similar to finding the x- intercept. Instead of setting "y" to zero you set "x" to zero and solve for "y".

DONE

y=3(0)-41

y intercept = (0,-41)

y intercept is when x=0

x intercept is when y=0

You just pug zero in for the variable you are not trying to find.

So y=3(0)-41
y=-41.

For the x variable do just the opposite

(0)=3x-41
-3x=-41
x= 13.7

There you go that's all you have to do.

Plugging in zero for x gives you the y intercept.

Plugging in zero for y gives you the x intercept.

Just make y=0 and the answer will be the x intercept. Just make x=0 and the answer will be the y intercept. This is 7th grade stuff.

when the equation is in slope intercept form (equation above) the last number is the y intercept so it is -49

Im not in 8th grade...
Wisconsins math program is stupid as hell, we just got a new program that is reteaching us everything we learned in algebra 1 "In order to gain a further understanding, in math". Dont think I'm in some stupid class because my math programs fucked up.
