When you have equations such as: 2x^2+5y^2=98, how would you graph it if the numbers don't go into each other evenly?

Tony -Even if the numbers do not divide "nicely", you can still find the lengths of the major and minor axis.  Here's how:, divide both sides by 98, now get it in standard form, simplifyFirst of all, this ellipse is centered at (0,0), agree?The major axis is always the bigger of the two denominators, so a^2=49 or a=7.  The endpoints of the major axis are (-7,0) and (7,0), right?Do the same for the minor axis:b^2 = 19.6, so b≅4.43So the endpoints of the minor axis are (0,4.43) and (0,-4.43).I'll leave the graphing to you!Hope that helps
