Question

Which of the following equations would make a line perpendicular to

AB if A = (-1,9) and B = (2, 14)

Answer 1

y=(3/5)x+3 -- This first option is correct!

Explanation:

Given - A = (-1,9) B = (2,14)

So, the slope of the line is

m = Y2-Y1/X2-X1 = m = 14-9/2-(-1)

m = 5/3

So, slope of perpendicular line to AB should be M1 = -3/5

So, the first option -- y=-3/5x+2 -- equation of perpendicular to give AB.

I hope this was helpful! :))

Answer 2

second one (y= -3/5x +2)
