You can put this solution on YOUR website!
you need to find the slope of the equation given, then reverse the slope to get the perpendicular line and use the point to solve for b.
-4y-5=3x put in slope intercept form
-4y=3x%2B5
y=%28-3%2F4%29x-5%2F4 y=mx+b so m=-3%2F4
Find perpendicular line:
y=mx%2Bb with point (6,5)
5=%28-4%2F3%29%286%29%2Bb find b
5=-8%2Bb
13=b
new line looks like:
y=%28-4%2F3%29x%2B13
