# Ellipse equation standard form

Since a = b in the ellipse below, this ellipse is actually a circle whose standard form equation is x² + y² = 9 Graph of Ellipse from the Equation The problems below provide practice creating the graph of an ellipse from the equation of the

## Equation of Ellipse

The standard form of the equation of an ellipse with center (0,0) ( 0, 0) and major axis parallel to the x -axis is x2 a2 + y2 b2 =1 x 2 a 2 + y 2 b 2 = 1 where a >b a > b the length of the major axis is 2a 2 a the coordinates of the vertices are (±a,0) (
