You can put this solution on YOUR website!
Note:

is the first point

. So this means that $\"x%5B1%5D=-2\"$ and $\"y%5B1%5D=5\"$ .\r
\n" ); document.write( "\n" ); document.write( "Also,

is the second point

. So this means that $\"x%5B2%5D=1\"$ and $\"y%5B2%5D=4\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"$ Start with the slope formula.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"m=%284-5%29%2F%281--2%29\"$ Plug in $\"y%5B2%5D=4\"$ , $\"y%5B1%5D=5\"$ , $\"x%5B2%5D=1\"$ , and $\"x%5B1%5D=-2\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"m=%28-1%29%2F%281--2%29\"$ Subtract $\"5\"$ from $\"4\"$ to get $\"-1\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"m=%28-1%29%2F%283%29\"$ Subtract $\"-2\"$ from $\"1\"$ to get $\"3\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the slope of the line that goes through the points

and

is $\"m=-1%2F3\"$ \r
