Answer 1

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

Answer 2

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

Answer 3

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