Answer:
a b and d
Step-by-step explanation:
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.
Solve for the x-max or h :\

plug it in to equation to get k:/

-8+16+3=11=k

solve for a by pluging (0,0)
then a= -11/4
