area of ellipse formula

Find the standard form of the equation for the ellipse whose major axis has end points (- 5, - 4) and (11, - 4) and whose minor axis has length 6. => ( x + 3 ) 2 6 4 + ( y - 4 ) 2 9 = 1 or ( x - 3 ) 2 9 + ( y + 4 ) 2 6 4 = 1 or x 2 + 3 y 2 = 1 or ( x - 3 ) 2 6 4 + ( y + 4 ) 2 9 = 1..
