-7x -7y = 21 
Y = 6 
Since they are giving you the value of 6 you just plug it in the equation 
-7x - 7(6) = 21 
-7x - 42 = 21 
 + 42. +42 
-7x = 63 
/-7. /-7 
X = -9

This is the form of a circle. Use this form to determine the center and radius of the circle.
 
        
             
        
        
        
First subtract h from h to get - 2h 
Then add 19 to both sides leaving you with 
-2h = -32 
Then divide by -2 on both sides 
H = 16
