Introduction
Have you ever noticed that some things increase at a steady rate, such as the cost of movie tickets or the distance traveled at a constant speed? These situations are called proportional rel...

A proportional relationship happens when two quantities change so that one is a constant multiple of the other, written as y = kx.
In this equation, k is the slope, representing the constant rate of change, or unit rate, showing how much y changes for every one-unit increase in x.
Since t...
