Respuesta :

Answer:

B

Step-by-step explanation:

First, find the y-intercept form of the equation:

x - y = 4

x - x - y = 4 - x

-y = 4 - x

-y = -x + 4

-y/-1 = -x/-1 + 4/-1 (to get the y positive)

y = x - 4

The y-intercept is -4. This means that a y-intercept two units above 4 would be -2. Whichever line crosses the y axis at the value of -2 is the answer (line B)

hope this helps :)
