Question

Find the x- and y-intercepts for the following equation.
−4x + 3y = 9

Answer 1

The y-intercept is when x=0

-4(0) + 3y = 9 -> 0 + 3y = 9 -> y = 3

The x-intercept is when y=0

-4x + 3(0) = 9 -> -4x + 0 = 9 -> x = -9/4

Answer 2

So, the y-intercept is (0, 3) and the x-intercept is (-9/4, 0)

Answer 3

All good now?

Answer 4

So for Find the x- and y-intercepts for the following equation. (Examples 1-3)
y = 4x + 8
would x =-2,0 and y= 0,8?

Answer 5

yes, you got it!
