Given:
Center of the ellipse is,
Minor axis length is,
A vertex of the ellipse is at (1, -3)
Now, distance between the center and the vertex is half of the length of the major axis.
Using distance formula for (-4, -3) and (1, -3), we get:
Therefore, the value of half of major axis is, . Also,
Now, equation of an ellipse with center is given as:
Plug in and determine the equation.
Therefore, the equation of the ellipse is:
