If the addition or subtraction of two linear equations results in the equation $0 = 9$ , then the graphs of those equations are perpendicular.

Question

Quizplus · Accepted Answer

The equation $0 = 9$ indicates that the system of equations is inconsistent, meaning there are no points of intersection; it does not provide information about the slopes of the lines, which determine if they are perpendicular.
