You can put this solution on YOUR website!
The slope, m, of a line that passes through two points, (x%5B1%5D, y%5B1%5D) and (x%5B2%5D, y%5B2%5D) is given by:
m+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
So, if you make the appropriate substitutions of the x- and y-coordinates from the two given points, (18, 11) and (9, 2), you can find the slope, m.
m+=+%282-11%29%2F%289-18%29
m+=+%28-9%29%2F%28-9%29 Simplify.
m+=+1
