Lines m and n are perpendicular. If the slope of line m is zero, then the slope of n isfind the slope of line n. If you were to sketch lines m and n, what type of lines would you sketch?

If the slope of line m was 0, then, then, in order to be perpendicular with line m, the slope of line n would be undefined because it would be a verticle line. m would be a horizontal line parallel to the x-axis, and n would be a verticle line parallel to the y-axis.
