Introduction: Direct Proportion vis Inverse Proportion

During the lesson, as an introduction, you were asked to enter 2 groups of equations into "Grapher" to observe the characteristics of each group of graphs, i.e. similarities (within the group of lines) and differences (between the lines in Groups 1 & 2).

Here are the 2 groups of equations:
Group 1: Equations that demonstrate direct proportion
Group 2: Equations that demonstrate inverse proportion


Group 1 graphs look like this:


Group 2 graphs look like this:
