Which function has a graph with a y-intercept of -4?
A. 2x – 4y = 8
B. 2x – 8y = -4
C. 4x – 2y = -8
D. 4x - 2y = 8

Respuesta :

the correct answer would be D. if you rearrange the equation, and cross out common factors, it equals -4

Answer:

D

slope is 2 and y-intercept is (0, -4)

Step-by-step explanation:

4x-2y= 8  move variable x to the right (change signs)

- 2y= -8 + 4x   Divide both sides by 2

y= -4 + 2x        reorder terms using communitive property

y = 2x  -4

y= mx + b
