I personally use y2-y1 over x2-x1 because it's simple. Plot two y values and two x values. The first ones you plotted are x1 and y1, the others are x2 y2. Now subtract y2-y1 and x2-x1. Afterwards, divide the y value by the x value, that will give you slope.
Vertex is (-2,-3) and it's a minimum.
D=(S+8)/C
S=DC-8
add 8 to both sides
S+8=DC
divide c from both sides
(S+8)/C=D
