Question 711664:  name the vertex of the parabola with the equation y^2 - 8y + 18 = x 
 Answer by lwsshak3(11628)      (Show Source): 
You can  put this solution on YOUR website! name the vertex of the parabola with the equation  
y^2-8y+18=x 
y^2-8y=x-18 
complete the square: 
(y^2-8y+16)=x-18+16 
(y-4)^2=(x-2) 
This is an equation of a parabola that opens rightwards. 
Its standard form of equation: (y-k)^2=4p(x-h), (h,k)=(x,y) coordinates of the vertex 
For given parabola: 
vertex: (2,4)
