Question 736556: Find the length of the minor axis for the ellipse defined by this equation:
(x+5)^2/81 + (y-5)^2/9=1
Answer by josgarithmetic(39618)   (Show Source):
You can put this solution on YOUR website! 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.
