Answer:
x = -1
Step-by-step explanation:
The green line is a vertical line has the same x - coordinate. If two points have the same x - coordinate, c , the equation of the line is x = c.
The x -intercept of a vertical line x=c is the point (c,0).
Except for the line x=0 , vertical lines do not have a y -intercept so x = -1
