Best ResponseYou've already chosen the best response.2hint: \(\bf \cfrac{(x{\color{brown}{ h}})^2}{{\color{purple}{ a}}^2}+\cfrac{(y{\color{blue}{ k}})^2}{{\color{purple}{ b}}^2}=1 \qquad center\ ({\color{brown}{ h}},{\color{blue}{ k}})\qquad vertices\ ({\color{brown}{ h}}\pm a, {\color{blue}{ k}}) \\ \quad \\ \cfrac{(x+2)^2}{25}+\cfrac{(y5)^2}{9}=1\implies \cfrac{(x{\color{brown}{ 2}})^2}{{\color{purple}{ 5}}^2}+\cfrac{(y{\color{blue}{ 5}})^2}{{\color{purple}{ 3}}^2}=1\)
