Answer:

x = 0

Step-by-step explanation:

linear equation y = mx + b, where m is the slope and b is the y intercept when x is 0.

m = change in y/change in x = -8-7/0 = undefine

so line is vertical at x = 0

Answer:

0

Step-by-step explanation:

m = slope

m = change in y/change in x

m = y2 - y1/x2 - x1

m = -8 - 7/0 - 0

m = -15/0

m = 0
