Question: Slope With Maple 10 And Simple Graph

I need to get the slope of this plotted line that I did, and I have no clue how. Here is the points I used: points := [[22, 100.19], [40, 200.19], [50, 300.19], [62, 400.19], [75, 500.19], [95, 600.19]] I'm not sure what do to, I tried slope[[22,100.19],[95,600.19]] so try and get the slope of the line between those two points, but nothing came up, it just went to the next line and said "slope".
