\n" ); document.write( " $\"4x+%2B+12y+=+-18\"$
\n" ); document.write( "Simplify to follow format -----> $\"y=mx%2Bb\"$
\n" ); document.write( " $\"12y=-18-4x\"$ ----> $\"cross%2812%29y%2Fcross%2812%29=%28-18-4x%29%2F12\"$
\n" ); document.write( " $\"y=%28-18%2F12%29-%284x%2F12%29\"$ , reduce
\n" ); document.write( " $\"y=%28-3%2F2%29-%281%2F3%29%28x%29\"$
\n" ); document.write( "Therefore, it has $\"slope=-1%2F3\"$ and y-intercept $\"highlight%28y=-3%2F2%29\"$
\n" ); document.write( "f(y)=0:
\n" ); document.write( " $\"0=%28-3%2F2%29-%281%2F3%29x\"$
\n" ); document.write( " $\"%28-1%2F3%29x=3%2F2\"$ --> $\"cross%28-1%2F3%29x%2Fcross%28-1%2F3%29=%283%2F2%29%2F%28-1%2F3%29\"$
\n" ); document.write( " $\"x=%283%2F2%29%28-3%2F1%29\"$
\n" ); document.write( " $\"highlight%28x=-9%2F2%29\"$ , x intercept.
\n" ); document.write( "We'll see in the graph:
\n" ); document.write( " --- see points (-9/2,-3/2) -- $\"system%28-9%2F2=-4.5%2C-3%2F2=-1.5%29\"$
