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 $x_1 = -2, x_2 = -2, y_1 = 8, y_2 = 3$

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

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

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

$5x + 10 = 0$
