1) $\"-x-3y=-4\"$ ------------> LINE EQN 1
\n" ); document.write( "it follows: $\"y=mx%2Bb\"$ ,
\n" ); document.write( " $\"-3y=x-4\"$
\n" ); document.write( " $\"y=%28-1%2F3%29x%2B%284%2F3%29\"$ ----> $\"slope=-1%2F3\"$ ; y-intercept= $\"4%2F3\"$
\n" ); document.write( "f(y)=0:
\n" ); document.write( " $\"x=%28-4%2F3%29%28-3%2F1%29=12%2F3=4\"$
\n" ); document.write( "f(x)=0:
\n" ); document.write( " $\"y=4%2F3\"$
\n" ); document.write( "2) $\"3x%2By=16\"$ ---------------> LINE EQN 2
\n" ); document.write( " $\"y=-3x%2B16\"$ ---> $\"slope=-3\"$ ; y-intercept = $\"16\"$
\n" ); document.write( "f(y)=0:
\n" ); document.write( " $\"3x=16\"$ ----> $\"x=16%2F3\"$
\n" ); document.write( "f(x)=0:
\n" ); document.write( " $\"y=16\"$
\n" ); document.write( "See graph:
\n" ); document.write( "

----> Green Line $\"3x%2By=16\"$ @ points (16/3,16); Red Line $\"-x-3y=-4\"$ @ points (4,4/3)
