Mathematics

Tems11 [23]2 years ago
5 0

Step-by-step explanation:

Since we have a vertical major axis, our ellipse is vertical.

The equation of a vertical ellipse is

\frac{(y - k) {}^{2} }{ {a}^{2} }  +  \frac{(x - h) {}^{2} }{ {b}^{2} }  = 1

where

(h,k) is the center

a is the semi major axis,

b is the semi minor axis

First, let plug in our center

\frac{(y + 3) {}^{2} }{ {a}^{2} }  + \frac{(x + 2) {}^{2} }{ {b}^{2} }  = 1

Semi means half, so

a is half of 14 which is 7

B is half of 8, which is 4.

\frac{(y + 3) {}^{2} }{49}  +  \frac{(x + 2) {}^{2} }{16}  = 1
