x^2+y^2=-9+11y
x^2=y
Type your answer as ordered pairs (x,y) with the order: from the smallest value of x to the largest
(1,1)
(3,9)
Solve by substitution of the second equation into the first to get
y+y2=-9+11y
(y-9)(y-1)=0
y= 1 or 9
Substituting each into the original equation gives the above.Don't forget the negative values to determine the other pairs.
