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.
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.
