the slope \"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"
\n" ); document.write( "Points (5,7) (\"4%2F7\", -1)
\n" ); document.write( "Substitute into the formula \"x%5B1%5D=5\", \"y%5B1%5D=7\", \"x%5B2%5D=4%2F7\", \"y%5B2%5D=-1\"
\n" ); document.write( "\"m=%28-1-7%29%2F%284%2F7-5%29=-8%2F%28-31%2F7%29=8%2A%287%2F31%29=56%2F31\"
