Answer:

X-int: (1/2 , 0) . Y-int: (0 , 4)

Explanation:

FOR X

To find the x-intercept, substitute in 0 for Y and solve for X.

0 = -8x + 4

1. Move 4 to the left side so it's -4 = -8x

2. Divide by -8 to isolate X so it's -4/-8 = x

3. The negatives cancel out and become positive

4. Answer: X = 1/2

FOR Y

To find the y-intercept, substitute in 0 for X and solve for Y.

Y = -8(0) + 4

1. Since anything multipled by 0 is 0, it simply becomes Y = 4.

Answer: Y = 4
