<h2>Explanation:</h2>The Cartesian coordinate system is formed by two perpendicular axes, which are the x-axis and y-axis. In this problem, we are given two lines:
- The line
is parallel to the y-axis and has an undefined slope.
- The line
is parallel to the x-axis and has a slope of zero.
Since the x and y-axes are perpendicular, then the lines are also perpendicular.
