Find the graph of the ellipses that have the following equations.
\dfrac{\left(x-2\right)^2}{4}+\dfrac{\left(y+1\right)^2}{9}=1
\dfrac{\left(x-1\right)^2}{4}+\dfrac{\left(y-1\right)^2}{16}=1
\dfrac{\left(x+2\right)^2}{1}+\dfrac{y^2}{4}=1
\dfrac{x^2}{9}+\dfrac{\left(y+1\right)^2}{25}=1
\dfrac{\left(x+3\right)^2}{16}+\dfrac{\left(y+1\right)^2}{4}=1
\dfrac{\left(x-1\right)^2}{25}+\dfrac{\left(y+3\right)^2}{9}=1
\dfrac{\left(x+2\right)^2}{36}+\dfrac{\left(y-2\right)^2}{9}=1
