Question

For the graph x = -42 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your answer with two or more sentences.

Answer 1

x - 42 is a straight vertical line passing through -42 on the x-axis ( point -42,0)
so the slope is infinite .
Another line with same slope and parallel to it would be x = 36.

A horizontal like with slope 0 is perpendicular to it It would have equation y any number so y = 6 would be an example.
