You can put this solution on YOUR website!
in order to graph this, you have to solve for y.
\n" ); document.write( "you start off with:
\n" ); document.write( "x^2 + 4y^2 = 64
\n" ); document.write( "subtract x^2 from both sides to get:
\n" ); document.write( "4y^2 = 64 - x^2
\n" ); document.write( "divide both sides by 4 to get:
\n" ); document.write( "y^2 = (64-x^2)/4
\n" ); document.write( "take square root of both sides to get:
\n" ); document.write( "y = +/- \"sqrt%28%2864-x%5E2%29%2F4%29\"
\n" ); document.write( "you could simplify further but it's not necessary.
\n" ); document.write( "you would graph 2 equations.
\n" ); document.write( "first equation would be:
\n" ); document.write( "y = \"sqrt%28%2864-x%5E2%29%2F4%29\"
\n" ); document.write( "and second equation would be:
\n" ); document.write( "y = - \"sqrt%28%2864-x%5E2%29%2F4%29\"
\n" ); document.write( "shown below:
