1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation

Answer:
E = (-14, 15)
Step-by-step explanation:
The midpoint relation is ...
M = (D +E)/2
2M = D +E . . . . multiply by 2
E = 2M -D . . . . subtract D
E = 2(-4, 8) -(6, 1) = (-8-6, 16 -1)
E = (-14, 15)
