SOLUTION: The points (5,k) and (k, 3) lie on a line perpendicular to a line with a slope of 3/4. What is the value of k?
So far I have arrived at {{{ 3/4 = (3-k)/(k-5)}}} using {{{ m=(Y2-Y1

Question 872292: The points (5,k) and (k, 3) lie on a line perpendicular to a line with a slope of 3/4. What is the value of k?
So far I have arrived at using but i do not know how to proceed from there.

the points are on the line perpendicular to a line with slope 3/4
so the slope of the line joining these points will be -4/3
cross multiply
-4(k-5)=3(3-k)
-4k+20=9-3k
k=11
