You can put this solution on YOUR website!
the equation slope(m) is: m=((first y value - second y value)/(first x value - second x value)
\n" ); document.write( "for the ordered pair (4, -7) and (-2, r) and slope of 8/3
\n" ); document.write( "m=((first y value - second y value)/(first x value - second x value)
\n" ); document.write( "8/3=((-7-r)/(4-(-2))
\n" ); document.write( "8/3=(-7-r)/(6)
\n" ); document.write( "16=-7-r
\n" ); document.write( "23=-r
\n" ); document.write( "r=-23 \n" ); document.write( "

\n" );
