Ok. To solve #8 you can look at your graph and the equation. At map distance 1 (x=1), y=8 because in your equation y=8x. Hope that helped and that you can do #8.
#9 you make a graph by graphing the coordinates x and y in the table. For example, the first point you would graph is (1,8) because you got that from the table.
#10. It gives 64km but that isn't in the window of the graph. So you're gonna use the equation. 64km is the real distance, so it is the y-coordinate. y = 8x 64 = 8x x = 8 8cm on the map
