Graphs of Linear Systems: Heart Rate Tracker

This Graphs of Linear Systems: Heart Rate Tracker interactive also includes:

Max out heart rates for males and females. Formulas of maximum heart rates provide the equations for a linear system. Pupils use the interactive to graph the equations for males and females and determine their points of intersection. The scholars then test points to find out if they are solutions to both equations.
