Answer:
Center is at (0,0)
Step-by-step explanation:
An equation of ellipse in standard form is:
Where center is at point (h,k)
From the equation of 
. First, we add 45 both sides:
Convert into the standard form with RHS (Right-Hand Side) equal to 1 by dividing both sides by 45:
Therefore, the center of ellipse is at (0,0) since there are no values of h and k.
