Question 675056
the slope of a line perpendicular to any line will be -ve reciprocal of that line the slope of a line  that passes through the  points (4, 11) and (-2, 1)is 
(1-11)/(-2-4)=-10/-6=5/3
so the the slope of the line perpendicular to the line that passes through the following points (4, 11) and (-2, 1) is -3/5
