The graph of the ellipse is

Step by step solution

Step 1.Given information

The equation of the ellipse is $\frac{{(x - 3)}^{2}}{25} + \frac{{(y + 2)}^{2}}{9} = 1$

Step 2. Concept used

The standard form of the ellipse with center not at the origin is $\frac{{(x - h)}^{2}}{a^{2}} + \frac{{(y - k)}^{2}}{b^{2}} = 1 Center (h, k), a > b \Rightarrow majoraxisishorizantal,sothedistancefromthecentertothevertexis a . b > a \Rightarrow major axis is vertical, so the distance from the center to the vertex is b .$

Step 3.Find the center and major axis

The equation of the ellipse is $\frac{{(x - 3)}^{2}}{25} + \frac{{(y + 2)}^{2}}{9} = 1$

Center $(h, k) = (3, - 2)$

25 > 9 \Rightarrow majoraxisishorizantalaxis a^{2} = 25 \Rightarrow a = \pm 5 Thedistancefromcentertoendpointsofmajoraxisis 5 b^{2} = 9 \Rightarrow b = \pm 3 Thedistancefromcentertoendpointsofminoraxisis 3

Step 4. sketch the ellipse

The graph of the ellipse is
