Shooting game (linear functions; slope; y-intercept)

Shooting game for two players. This game is about linear functions, slope and y-intercept. Players must adjust the shot so that it will take off from the blue dot and hit the green target by adjusting the values of m and n. Beginners should be allowed to see the axis and the grid and points should be placed only at integer values. Players may have 5 or 3 shots depending on the level of difficulty. Expert players may have only one shot (with the grid on).
