@triciaal I believe one of the points is (6,3), can you help me to see if I am correct?

OpenStudy (triciaal):

First the question is asking for the equation of the line perpendicular to AB and passes through point P (-4, 7) slope of AB = 4 slope of perpendicular = -1/4 using the point P : 7 = -1/4(-4) + b solving for b, equation becomes y = -1/4 x + 6

OpenStudy (triciaal):

don't agree, when x = 6 y = -1/4(6) + 6 = 9/2 so (6, 9/2)
