Question 971546: what is the equation of a line perpendicular to the line y=-3/2x+4, passing through the point (3,9)? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Perpendicular lines have slope products =-1
The slope of the line desired is 2/3, and it goes through (3,9)
Use point-slope formula
Y-y1=m(x-x1)
Y-9 =2/3 (x-3)
Y-9=(2/3)x - 2
Y=(2/3)x + 7
