Question

find the y-intercept
3x+4y=36

Answer 1

Set \(x=0\) and solve for \(y\).

Answer 2

For the y-intercept, x = 0
3(0) + 4y = 36
4y = 36
y = 9
Hence the y-intercept is (0, 9)

Answer 3

i thpught u divded -4 to 36 and 3

Answer 4

and then i got -3/4x+9

Answer 5

That's correct. That's slope intercept form (y = mx + b), here "b" is your y-intercept.

Answer 6

ya and then u graph it right

Answer 7

Sure. If you need to. Then your slope is "m" (-3/4)

Answer 8

So then from 9, you can either move down 3 and right 4, or up 3 and left 4.

Answer 9

Something like that, yes ;)

Answer 10

cause i went high

Answer 11

You can also find the x-intercept by setting y = 0, and solving for x.

Answer 12

oh ok thanks
