y=mx+b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First find the slope (m) using the difference of the y's over the difference of the x's.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%280-%28-4%29%29%2F%284-0%29\"$
\n" ); document.write( " $\"4%2F4\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the slope is 1\r
\n" ); document.write( "\n" ); document.write( "y=x+b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Plug in one of the points, it doesn't matter which one.\r
\n" ); document.write( "\n" ); document.write( "0=4+b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve for b
\n" ); document.write( "b=-4\r
\n" ); document.write( "

\n" ); document.write( "y=x-4 \n" ); document.write( "
