You can put this solution on YOUR website!
I assume the line is straight forward and passes thru whole number coordinates
\n" ); document.write( ":
\n" ); document.write( "if so then you simply take the rise over the run
\n" ); document.write( ":
\n" ); document.write( "in other words the change in the y direction over the change in the x direction ....pay attention to direction
\n" ); document.write( ":
\n" ); document.write( "for example if (1,1) is on the line and you have another point on the line at
\n" ); document.write( "(3,4) ...you count up 1,2,3 units one the y coordinate(positive-if you move down that is negative)and then you move 2 units to the right(positive again-if you move left that is negative).....so you have +3/+2=3/2 slope. That makes sense because lines with positive slopes rise as you move from left to right and lines with negative slopes fall as you move from left to right.
