Focal length of ellipse
WebAn ellipse is defined as two locations whose sum of distances from each other point on the ellipse is always the same. They are lying on the elliptical. The focal length of the ellipse is the distance between each focus and the center. Also read: Differential Equation How to find Foci of an Ellipse? [Click Here for Sample Questions] WebFind an equation of the ellipse with foci ( − 3 , 4 ) and ( 9 , 4 ) and the length of the major axis 14 . The sum of the focal radii is 14 , so 2 a = 14 and a = 7 .

I found that one of the foci of the ellipse is (2; 0). If I express the equation of the line L that is requested as L: y = mx + b, and replace the coordinates of the point (2; 0), I obtain b = -2m. With this we have L: y = m (x-2).
