Question

Line l has a slope of 98. The line through which of the following pair of points is perpendicular to l?

A. (−9,−6),(3,3)
B. (9,−2),(−6,6)
C. (−5,−6),(3,3)
D. (3,−5),(−6,3)

Answer 1

m =( Y2 - Y1)/ (X2-X1)

m =( 3-(-5))/ (-6-3)

m = - 8/9

I am assuming you meant a slope of 9/8 in your original question, so the points perpendicular to I are answer D.

Perpendicular means the slope is opposite reciprocal of your first slope given.
