Question

What is the x-intercept and y-intercept of the graph of 4x - 8y = 32?

A) x-intercept = (0, -4); y-intercept = (8, 0)

B) x-intercept = (-8, 0); y-intercept = (0, 4)

C) x-intercept = (8, 0); y-intercept = (0, -4)

D) x-intercept = (0, 4); y-intercept = (-8, 0)

Answer 1

x intercept is the point where the line intersects the x axis. on the x axis, y =0.
so substitute y = 0 in the equation to find the x intercept.
similarly substitute x=0 in the equation to find the y-intercept.

Answer 2

what does it mean when he says "x-intercept" = it means the graph is touching the x-axis so, y=0
hence, substitute 0 (zero) for y in your eqaution and you will find the x-intercep (x,0)

Answer 3

IDK

Answer 4

substitute y = 0 in your equation and post what you get.

Answer 5

is it D?

Answer 6

Why are you guessing the answer? just substitute y = 0 in your equation and see what you get.

Answer 7

4x - 8y = 32?

-8y = 32 - 4x
y = 32/(-8) -4x/(-8)

y = -4 + (1/2)x
this is you equation. Plug in 0 into X and you'll find the Y-intercept (0,y)
Plug in 0 into Y and you'll find the X-intercep (x,0)

Answer 8

A is the answer?

Answer 9

no, try again.

Answer 10

C is my final answer lol

Answer 11

Yup yo got it

Answer 12

YES!
