Question 217058: Could someone please help me with this problem. It says to graph the ellipse x%5E2%2B4y%5E2=64 I tried solving for Y but i came out with y=4-1/2x which didnt seem to work. I would really appreciate any step by step help.

You can put this solution on YOUR website!
You can start with a graph of the inequality x%5E2%2B4y%5E2+%3C+64 to get you started:
graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+x%5E2%2B4y%5E2+%3C+64+%29
This site has a general graphing calculator that plots inequalities.
You can set x = 0 and find out where the ellipse cross the Y axis, by solving for Y: 0%5E2+%2B+4y%5E2+=+64, which is easy (y=%2B-4). Then do the same to find out where it crosses the X axis with Y=0: x%5E2+%2B+4%2A0%5E2+=+64 (x=%2B-8).
