y-y1 = m(x-x1)
\n" ); document.write( "y-(-1) = 3(x-(-2))
\n" ); document.write( "y+1 = 3(x+2)
\n" ); document.write( "y+1=3x+6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract y from each side:
\n" ); document.write( "1=3x-y +6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract 6 from each side:
\n" ); document.write( "1-6=3x-y
\n" ); document.write( "-5=3x-y
\n" ); document.write( "3x-y=-5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here is a NEAT trick! Check the answer by substituting the point (-2,-1) to see if it works:
\n" ); document.write( "3x-y=-5
\n" ); document.write( "3(-2) -(-1) = -5
\n" ); document.write( "-6 + 1 = -5
