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
Take 16x divide it by 2 and square it. 16/2= 8. 8^2= 64. So, the first step will be to add 64 to both sides.
