Use the definition of slope for the unknown point (x,y) and given point (3,-1).\r

\n" ); document.write( "\n" ); document.write( "\"-1=%28y-%28-1%29%29%2F%28x-3%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-1=%28y%2B1%29%2F%28x-3%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-1%28x-3%29=y%2B1\"------------this is by the symmetric property for equality, the point-slope form for the equation.
