 Question 27530: find the slope of any line perpendicular to the line through points(0,5) and (-3,-4) I started with y=0(x)+ 5, y=-3x-4 i am not sure what to do next.Answer by venugopalramana(3286)   (Show Source): You can put this solution on YOUR website!find the slope of any line perpendicular to the line through points(0,5) and (-3,-4) I started with y=0(x)+ 5, y=-3x-4 i am not sure what to do next. THAT IS NOT THE WAY FIRST FIND SLOPE OF THE LINE JOINING THE 2 POINTS ..IT IS..(Y2-Y1)/(X2-X1)=(5+4)/(0+3)=9/3=3 NOW SLOPE OF THE PERPENDICULAR LINE = -1/3 RULE FOR PERPENDICULAR LINES =PRODUCT OF SLOPES = -1
