You can put this solution on YOUR website!
First you need to put these equations in the line form [Y=mX+b] where the [m] term=slope & the [b] term=y intercept.
\n" ); document.write( "7x+2y=9
\n" ); document.write( "2y=-7x+9
\n" ); document.write( "y=-7x/2+9/2
\n" ); document.write( "y=-3.5x+4.5 (red line)
\n" ); document.write( "4x+5y=6
\n" ); document.write( "5y=-4x+6
\n" ); document.write( "y=-4x/5+6/5 (green line)
\n" ); document.write( " $\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+-3.5x+%2B4.5%2C+-4x%2F5+%2B6%2F5%29+\"$ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions -3.5x +4.5 and -4x/5 +6/5). \n" ); document.write( "
