Remark
All vertical lines are of the form x = a. The y value only places where the point is on the grid.
For this particular question the x value of the point is where the vertical line is. At x = -2 draw a vertical line. The graph shows what this looks like.
The graph (x = - 2) is in red.
The point (-2,10) is green.
