This is a equation for ellipse that I made

I'd like to get a coordinate of points on this ellipse

x coordinate starts from -4.9 and increase by 0.1

 

How can I get y coordinate and make x and y coordinate to table?

Did you get anywhere with this?

I think the answer to your question is 'with difficulty'.  It requires formulating and solving a quadratic equation in y and the formula is not well behaved near x=5.  A better curve can be obtained by using the polar coordinate ϑ as a parameter and calculating the radius r and, from that, the cartesian coordinates (x,y) .
