The ellipse passes through
Given:
The points
Now let us find the equation to the ellipse.
We know that the equation of the ellipse whose axes are x and y β axis is given as
Let us substitute the point (1, 4) in equation (1), we get
Let us substitute the point (-6, 1) in equation (1), we get
Let us multiply equation (3) by 16 and subtract with equation (2), we get
Or,
So,
So from equation (2),
So the equation of the ellipse can be given as
β΄Β The equation of the ellipse is
