You can put this solution on YOUR website!
x = -12
\n" ); document.write( "------
\n" ); document.write( "For any value of y, x = -12
\n" ); document.write( "That's a line 12 units left of the y-axis and parallel to the y-axis.
\n" ); document.write( "Slope = infinity, or undefined.
\n" ); document.write( "--------------
\n" ); document.write( "To calculate it:
\n" ); document.write( "slope, m = diffy/diffx = diffy/0
\n" ); document.write( "
\n" ); document.write( "
\n" );
