P is (0,T)
slope of CD = 2/-3 = -2/3
slope of PC is then 3/2
so PC is
y = (3/2)x + b
at C, x = -3 and y = -6
-6 = 1.5 (-3) + b
b = -6 + 4.5 = -1.5
so
y = 1.5 x - 1.5
on the x axis when y = 0
x = 1

P at (1,0)
A line segment has endpoints C(-3,-6) and D(-6,-4). Point P is such that PC is perpendicular to CD. Determine the coordinates of P if P is on the x-axis.
