Question

Line C passes through the points (-3,-6) and (-1,-12). What is the slope of the line perpendicular to the line C

Answer 1

The slope of the line perpendicular to the line C is 1/3.

Explanation:

m=(y2-y1)/(x2-x1)

m=(-12-(-6))/(-1-(-3))

m=(-12+6)/(-1+3)

m=-6/2

m=-3

perpendicular lines have negative reciprocal slopes.
