You can put this solution on YOUR website!
Use the definition of slope:
\n" ); document.write( " $\"slope=rise%2Frun\"$ \r
\n" ); document.write( "\n" ); document.write( "When you have two points ( $\"x%5B1%5D\"$ , $\"y%5B1%5D\"$ ) and ( $\"x%5B2%5D\"$ , $\"y%5B2%5D%29\"$ ),
\n" ); document.write( "Rise = $\"y%5B2%5D-y%5B1%5D\"$ and Run = $\"x%5B2%5D-x%5B1%5D\"$ .\r
\n" ); document.write( "\n" ); document.write( "Using the information from the problem, we have:
\n" ); document.write( " $\"slope=rise%2Frun\"$
\n" ); document.write( " $\"2=%287-3%29%2F%28x-4%29\"$
\n" ); document.write( " $\"2=4%2F%28x-4%29\"$
\n" ); document.write( " $\"%28x-4%29%2A2=4%2Fcross%28x-4%29%2Across%28x-4%29\"$
\n" ); document.write( " $\"%28x-4%29%2A2=4\"$
\n" ); document.write( " $\"%28x-4%29=2\"$
\n" ); document.write( " $\"x=6\"$
\n" ); document.write( " \n" ); document.write( "
