perpendicular means that the slopes are negartive inverses, aka slope1 times slope2=-1 y=mx+b slope=m y=-1/2x-2 slope=-1/2 we need to find negative inverse -1/2 times what=-1 answer is 2 y=2x+b input the point (2,-2) to find b (x,y) (2,-2) -2=2(2)+b -2=4+b minus 4 from both sides -6=b y=2x-6 the equtaion is y=2x-6
