Answer:
y = -12
Step-by-step explanation:
You first calculate the x coordinate using the equation x =  , which in this case is
, 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
 
        
             
        
        
        
0.12 x 0.1 = 0.012  I think
        
             
        
        
        
For this question, the equation I got was (x+3)^2 + (y-6)^2 = r^2.
