Which part corresponds to the variable, b, in your given ellipse equation? The minor axis length is taken as b in the standard form equation for an ellipse, which is the way that your equation is given.

Just to handle some confusion, when the major axis of ellipse is on a horizontal line, a is under the x^2 expression and b is under the y^2 expression. When the major axis of ellipse is on a vertical line, a is under the y^2 expression and b is under the x^2 expression. This is just one more detail to remember about ellipse equations in standard form.
