Question 715517
A(7,-1) and B(-4,2)

mid point co-ordinates x=(7+(-4))/2=3/2
y=(-1+2)/2= =1/2

(3/2, 1/2)

A(7,-1) and B(-4,2)

slope = ((2-(-1))/(-4-7)

slope=- 3/11

the slope of line perpendicular to this line will have slope of 11/3

m=11/3  , point (3/2, 1/2)

y-(1/2) = 11/3( x-(3/2))

y-1/2 =11/3(2x-3)/2)

simplify

2*3(y-1/2) = 11(2x-3)

6y-3=22x-33

6y=22x-30

y=(11/3)x -5
