Students use their knowledge of cartesian coordinates and linear equations to pop bubbles with a laser. The bubbles have integer values which the student sums to score points.

The student is given a starting point for a 'laser' and is asked to enter coordinates for a finishing point. The goal is to choose a point that means the laser pops as many positive bubbles and as few negative bubbles as possible.
Only the positive quadrant of the coordinate plane is used.
