Correct Answer
A. A

Explanation
Use the variable assignments from the quadratic formula to find -b/2a. b= -8 and a = -2. So, -b/2a = 8/-4=-2. The x value is -2.

Now substitute -2 into the original equation. y=-2(-2)^2 - 8(-2) -1 and simplify. Watch your signs. You should get y= -8+16 -1 which is 7. So the answer is A.

Explanation
Literally an exercise in matching the locations. 8x-1 is in the same location as 5x + 2, therefore they are equal. 8x-1=5x+2
subtract 5x from both sides
add 1 to both sides
3x =3
x=1

For y, 2y-4 =0
2y = 4
y =2
