The ellipse intercepts are (0,7), (5,0), (0,-7) and (-5,0)
The general equation for an ellipse with center (0,0) and width 2a and height 2b is given by:
[tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]
We can check in the graph and in the intercepts that a = 5 and b = 7.
Therefore we have:
[tex]\frac{x^2}{5^2}+\frac{y^2}{7^2}=1[/tex]
