x = -2

#### Explanation:

This is a special case of the equation of a line in that it's slope is undefined and it is parallel to the y-axis. The line passes through all points in the plane with the same x-coordinate and has equation

y = cwhere c is the value of the x-coord.

In this case the line passes through (-2 ,1) and it's equation isx = -2

All vertical lines only have an

Seeing that the x-value of the point is -2, it means that this is the value of
