This activity will give you some practice identifying the slope of a line. A good trick is to find two points on the line with integer coordinates. Then, you can calculate rise/run between those two points. Check the "Hint" box to see those points with integer coordinates. (Technical note: if you are using the Tab key to move focus between objects and it doesn't work, try Shift+Tab instead.)
See if you can get 10 in a row correct and fill the pie!
