The Consistent Player in Mathematics: How to Understand the Constant Rate of Change
A constant rate of change means the output changes by the same amount for every equal change in the input, which is what makes the graph a straight line. To test for it, check whether the ratio of change is the same across every pair. The examples below work through that. When you think of […]
The Secret Decoder Ring of Proportional Relationships: How to Find The Constant of Proportionality
The constant of proportionality is the ratio of y to x in a proportional relationship, and it stays the same for every pair. Find it by dividing one output by its input, then check it against another pair. The examples below show the method in tables, graphs, and equations. Dive headfirst into the world of […]
