What is the equation of the following graph?

This is a vertical ellipse since it's taller than it is wider. That means that y is the transversal axis, aka the major axis. The formula for this type of ellipse is

where h and k are the center of the ellipse and a is the number of units from the center along the minor axis to the outside of the ellipse and b is the number of units from the center along the major axis to the outside of the ellipse. Here, our h and k are, respectively, (0, -3), a = 1 and b = sqrt(3). Fitting those values into our formula we have the equation as

.

That's your answer!

answer: a

step-by-step explanation:

10.2 units

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
