You can put this solution on YOUR website!
Let m= {18-(-6)}/ { 9- 3} = 24 /6 = 4
\n" ); document.write( ".
\n" ); document.write( "m= (y2-y1)/(x2-x1)
\n" ); document.write( ".
\n" ); document.write( "using the point slope eqn with extreme coordinate pairs
\n" ); document.write( ".
\n" ); document.write( "y-y1 = m (x-x1)
\n" ); document.write( ".
\n" ); document.write( "y-18 = 4(x-9)
\n" ); document.write( ".
\n" ); document.write( "y-18 = 4x -36,,,,,,,subtracting y,, and adding 36 to both sides
\n" ); document.write( ".
\n" ); document.write( "18 = 4x -y
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "checking, y=4x -18,,,,,,all coordinates match ,,,,,ok
\n" ); document.write( " \n" ); document.write( "
\n" );
