10-61.

Graph each of the following ellipses. State the locations of the vertices, co-vertices, and focal points.

1. $\frac { x ^ { 2 } } { 4 } + \frac { y ^ { 2 } } { 9 }=1$

This ellipse is centered at $(0, 0)$. It has a 'horizontal radius' of $2$.

1. $\frac { ( x + 2 ) ^ { 2 } } { 25 } + \frac { ( y - 1 ) ^ { 2 } } { 16 }=1$

This ellipse is centered at $(−2, 1)$. It has a 'vertical radius' of $4$.
