Question

If line AB contains the points (6, -2) and (-3, 16), what is the slope of a line perpendicular to line AB ? Enter your answer as a decimal.

Answer 1

Do you know how to find the slope of those 2 points?

Answer 2

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

Answer 3

Yeah I do, just double checking.

Answer 4

m=(16+2)/(-3-6)
m=(18)/(-9)
m=-2

Answer 5

Okay thanks

Answer 6

then to find the perpendicular slope, you have to take the negative reciprical of that
so the perpendicular slope is 1/2

Answer 7

as a decimal, the answer is 0.5
