Standard Form for the equation of an ellipse with a vertical major axis:
Standard form for the equation of an ellipse with a horizontal majoraxis:
9(x2+6x+9-9) + 4(y2-2y+1-1) +49=0
9(x+3)2 + 4(y-1)2=36
9(x+3)2 + 4(y-1)2 =1
(x+3)2 + (y-1)2 =1
A calculator will help to simplify the equations involved in an ellipse but not graphing. There are websites that will help with graphing ellipses. All you have to do is put in the vertices and the covertices; the equation will be graphed automatically.
