The graph of an ellipse by translation is shown below:

Step by step solution

01

Step 1.Given information

The given ellipse is (x-5)29+(y+4)24=1.

The given ellipse will have the same size and shape as the ellipse x29+y24=1whose center is (0,0).

02

Step 2. Find whether the major axis is horizontal or vertical. 

The standard form of an ellipse with center (0,0)is given by localid="1645700232210" x2a2+y2b2=1(1).

Compare the equation x29+y24=1with the equation (1)to find a2and b2.

a2=9b2=4

Since 9>4and 9 is in thex2 term, the major axis will be horizontal.

03

Step 3. Find the endpoints of the major axis and the minor axis.

The value is a2=9.

This implies that a=±3.

The coordinates of the vertices are (3,0)and (-3,0).

The value is b2=4.

This implies that b=±2.

The coordinates of the endpoints of the minor axis are(0,2) and (0,-2).

04

Step 4. Draw the ellipse centered at the origin.

The graph of an ellipse is shown below:

Step 5. Translate the graph of x29+y24=1 by determining the center of the given equation (x-5)29+(y+4)24=1.

The standard form of an ellipse with center (h,k)is given by (x-h)2a2+(y-k)2b2=1.

The equation (x-5)29+(y-(-4))24=1is in standard form and the center is (5,-4).

Now, translate the graph of x29+y24=1five units to the right and then down4units.

Step 6. Draw the graph of a new ellipse whose equation is (x-5)29+(y+4))24=1.

The graph of a new ellipse is shown below:
