    as a matter of fact, you can pretty much do this one with your eyeballs, if it is clear that the center is \((0,0)\)

    should be clear since that is half way between \((-4,0)\) and \((4,0)\) so your equation is going to look like \[\frac{x^2}{a^2}-\frac{y^2}{b^2}=1\] you only need \(a\) and \(b\) which you are given in the question

    so the equation is \[\frac{ x ^{2} }{ 4^{2}}+\frac{ y ^{2} }{ 5^{2}}=1\]
