Introduction

Some relationships have a constant rate of change and begin at zero. These relationships can be represented by an equation of the form y = mx. This form is useful for describing pro...

Imagine reading a book and completing 8 pages each day.

To represent the total number of pages read with an equation, let x be the number of days, and let y be the total number of pages read.

Then, we can write: y = 8x.

Equations like this are written in the form: y = mx. Here, m is the slope, or the constant rate of change.
