Linear Graphs – Gradient-Intercept Method – Worksheet C In this competitive activity students attempt to destroy enemy ships using equations of lines. You may want to specify exactly what type of equation students must use. You can increase/decrease the time to play by adding/removing ships. The worksheet is provided in 2 sizes.

Use equations of a straight line to defeat the enemy fleet! Interceptor Scout Heavy Lifter Mothership
Draw the boxes for each ship on your grid. One ship must be in each quadrant. To fire a shot, state the equation of a straight line. A shot hits a box if it goes through or beside it. Only one box is destroyed per shot. If hit, the player must state the quadrant and the ship.
If you need to, fold your paper to show your opponent where the shot/line should be!
Only cross off one box per hit. 𝑦=5 Hit, mothership, quadrant ①. Only cross off one box per hit.
Only cross off one box per hit. 𝑦=𝑥+4 Hit, mothership, quadrant ①. Only cross off one box per hit.
Only cross off one box per hit. 𝑦=2𝑥+1 Hit, mothership, quadrant ③. Only cross off one box per hit.

Players fire a laser shot across the galaxy by stating the equation of a straight line. Record your shots in the OPPONENT grid. A shot hits if it goes through or beside a ship’s box. 1 shot = 1 box destroyed The player must state which ship it hit & in which quadrant. A ship is destroyed when all its boxes have been hit.
