There is a formula for the slope between two points that looks like this:
\n" ); document.write( " $\"m=+%28rise%29%2F%28run%29+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+\"$
\n" ); document.write( ".
\n" ); document.write( "Since they gave you:
\n" ); document.write( "(6,7) and (2,-8)
\n" ); document.write( ".
\n" ); document.write( "then
\n" ); document.write( "(x[1],y[1])=(6,7)
\n" ); document.write( "(x[2],y[2])=(2,-8)
\n" ); document.write( ".
\n" ); document.write( "Plugging it in:
\n" ); document.write( " $\"m=+%28rise%29%2F%28run%29+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+\"$
\n" ); document.write( " $\"m=+%28rise%29%2F%28run%29+=+%28-8+-+7%29%2F%282-6%29+\"$
\n" ); document.write( " $\"m=+%28rise%29%2F%28run%29+=+%28-15%29%2F%28-4%29+\"$
\n" ); document.write( " $\"m=+%28rise%29%2F%28run%29+=+-15%2F4+\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
