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:
x%5E2%2Fa%5E2+%2B+y%5E2%2Fb%5E2+=+1
Your equation is:
x%5E2%2B25y%5E2+=+25 If you divide both sides by 25, you'll get...
x%5E2%2F25+%2B+y%5E2+=+1 which can be rewritten as...
x%5E2%2F5%5E2+%2B+y%5E2%2F1%5E2+=+1 Compare this with the standard form:
x%5E2%2Fa%5E2+%2B+y%5E2%2Fb%5E2+=+1 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.
