Answer:
y = -12
Step-by-step explanation:
You first calculate the x coordinate using the equation x =
, which in this case is
.
Then plug that x value into the equation to get the y coordinate:
4(-1)²+8(-1)-8 = -12
First you need to simplify the left side of the equation to get

Then you add by two on both sides to get

Finally you divide by 2 on both sides to get
