The slope is -13what is the slope of its perpendicular?

The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.

Perpendicular line = - 1/gradient = - 1/2/3 = - 3/2

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of a line that is...
