Question

i vneed help finding the y intercept of this equation. 5x-8y=120

Answer 1

the y intercept is where the graph intersects the y axis

Answer 2

so at the y-axis you know the x point is 0. so plug in 0 for x and solve for y. That will give you the y-intercept

Answer 3

can u show me how to do that

Answer 4

so you should have 5(0)-8y=120

Answer 5

then 5 times 0 is zero so you get -8y=120.

Answer 6

then divide both sides by -8..and you will get your y-intercept

Answer 7

thank you

Answer 8

so is the answer 15
i mean -15

Answer 9

yes
