\n" ); document.write( "Line Eqn's:
\n" ); document.write( " $\"x+-+3y+=+9+\"$ , EQN 1
\n" ); document.write( " $\"5x+-+15y+=+45+\"$ ,divide the whole eqn by 5
\n" ); document.write( " $\"%285x%2F5%29-%2815y%2F5%29=45%2F5\"$
\n" ); document.write( " $\"x-3y=9\"$ , EQN 2=EQN1
\n" ); document.write( "Via Slope-intercept Form: $\"y=mx%2Bb\"$
\n" ); document.write( " $\"3y=x-9\"$ ---> $\"cross%283%29y%2Fcross%283%29=%28x-9%29%2F3=%281%2F3%29x-%289%2F3%29\"$
\n" ); document.write( " $\"y=%281%2F3%29x-3\"$ ---> Line eqn.
\n" ); document.write( " $\"f%28y%29=0\"$
\n" ); document.write( " $\"%281%2F3%29x=3\"$
\n" ); document.write( " $\"highlight%28x=9%29\"$
\n" ); document.write( " $\"f%28x%29=0\"$
\n" ); document.write( " $\"highlight%28y=-3%29\"$
