Question

4x+5y=20
How do I find the y AND x intercepts of this question?

Answer 1

Incomplete

Answer 2

To find the y-intercept, set x=0. To find the x-intercept, set y=0.

Answer 3

I understand that part, but after that I get confused...

Answer 4

y-intercept, plug in 0 for x in the equation. 4*0+5y=20
x-intercept, plug in 0 for y in the equation. 4x+5*0=20

Find x for y-intercept and y for x-intercept.

Answer 5

so for the y intercept I would subtract the 4y from the 20 as well as the 4x?

Answer 6

4x I mean

Answer 7

I will show solution for y-intercept
4*0+5y=20
5y=20
y=4
So the y-intercept is (0,4)

Try the same thing for x-intercept.

Answer 8

I see, thank you!

Answer 9

Welcome ^^

Answer 10

so if Im doing this right, the x intercept is 5?

Answer 11

(5,0) Yep.
