what is the equation that represents a line that is perpendicular to y=2/3x-5 that passes through (6,12)

Question

 y = 2/3x-5 passes through (6,12) what equation represents it

Answer 1

y = mx + b

 

Its slope is

 

m = -1/(2/3) = -3/2

 

So far, we have

 

y = (-3/2)x + b

 

Get b from the given point.

 

12 = (-3/2)(6) + b

 

b = 21

 

y = (-3/2)x + 21
