Question

If AB contains the points (19,3) and (-5,-13), what is the slope of a line perpendicular to AB? Enter your answer as a decimal.

Answer 1

\[m1 = (y_{2}-y_{1})/(x_{2}-x_{1})\]
Does this formula look familiar to u?

Answer 2

Kinda of, yes

Answer 3

this is how we plug it
let (x1,y1) = (19,3) and (x2,y2) = (-5,-13)

Answer 4

So I get (-13-(-3) divided by (-5-19) right?

Answer 5

yes

Answer 6

(-13 - 3)/(-5 - 19) =??
can u solve it?

Answer 7

yeah I think I got it from here, thank you!

Answer 8

Anytime :3
