Question

What is the slope of the line that is perpendicular to the line that goes through the two points (-8, 3) and (4, 27)?

m= lype youiſ answer

Answer 1

-1/2 or -0.5

negative half

Explanation:

slope of regular line= (y1-y2) / (x1-x2)

(27-3) / (4 - -8)

24 / (4+8)

24 / 12 = 2

the slope of a perpendicular line is the negative reciprocal

the negative reciprocal of positive 2/1 (2 as a fraction) is:

negative half: -1/2 or -0.5
