Description

This is part two of a two-part E-example from the National Council of Teachers of Mathematics that allows users to drag a slider on an interactive graph to modify a rate of change (cost per minute for phone use). They also learn how modifications in that rate affect the linear graph displaying accumulation (the total cost of calls). In this part, the cost per minute for phone use changes after the first sixty minutes of calls. E-examples are selected from the electronic version of the Principles and Standards for School Mathematics (PSSM). Less
