Which point can be found using the vertical line x = –9 and the horizontal line y = 8?

ANSWER

The point is


EXPLANATION
When two nonparallel lines are drawn on the same plane, they will intersect at a unique point. This point represents the solution to the two systems of equations represented by the lines.

The vertical line


and the horizontal line


will intersect at


This is the unique solution to the two equations.
