Equation of the diameter is

#5x + 0y + 10 = 0#

Equation of the diameter, given two points (one is the end point and the other center) is
#(y-y_1) / (y_2-y_1) = (x-x_1) / (x_2-x_1)#

Given #x_1 = -2, x_2 = -2, y_1 = 8, y_2 = 3#

#(y - 8) / (3-8) = (x-(-2)) / (((-2)-(-2))#

#(y-8) / (-5) = (x+2) / 0#

#(-5)(x+2) = 0#

#5x + 10 = 0#
