This looks suspiciously like an ellipse!
The standard form of the equation of an ellipse with center @ (0,0) and major axis on the x-axis is:

Your equation is:
If you divide both sides by 25, you'll get...
which can be rewritten as...
Compare this with the standard form:
and you'll see that a = 5 and b = 1, so you have the equation of an ellipse with center @ (0,0), semi-major axis = 5 and semi-minor axis = 1.
