1. $\"2x-y=4\"$
\n" ); document.write( "2. $\"2x-y=6\"$
\n" ); document.write( "Let's make these two equations into slope-intercept form, y=mx+b.
\n" ); document.write( "1. $\"2x-y=4\"$
\n" ); document.write( " $\"2x-4=y\"$
\n" ); document.write( " $\"y=2x-4\"$
\n" ); document.write( "Slope = 2
\n" ); document.write( "Y-intercept = -4
\n" ); document.write( " $\"+graph%28+300%2C+300%2C+-10%2C+10%2C+-10%2C+10%2C+2x-4%29+\"$

\n" ); document.write( " $\"2x-6=y\"$
\n" ); document.write( " $\"y=2x-6\"$
