You can put this solution on YOUR website!
The slope of a line is $\"rise%2Frun\"$ which is the change in Y divided by the change in X. Since they are giving you 2 points through which the line goes, you can find the slope as follows:
\n" ); document.write( " $\"%28y2-y1%29%2F%28x2-x1%29\"$
\n" ); document.write( "Which for the 2 given points, is:
\n" ); document.write( " $\"%282-%28-3%29%29%2F%28-5-%28-5%29%29\"$
\n" ); document.write( "Simplifying this gives you a zero in the denominator, which means the slope of this line is infinite - i.e. it is a vertical line (a line parallel to the Y-axis).\r
