Question

PLEASE HELP!!!

Find the x and y intercepts for8x - 16y= 64.

A. x=4; y = 8

B. x=8;y = 4

C. x=8; y = -4

D. x=1/4; y = 8

Answer 1

C. x =8; y = -4

Explanation:

To find the x and y intercepts, substitute with zero.

8x - 16y = 64

Finding the x-intercept:

8x - 16(0) = 64

8x = 64

Divide both sides by 8.

x = 8

Finding y-intercept:

8(0) - 16y = 64

-16y = 64

Divide both sides by -16.

y = -4
