Class, One of the most common examples of using the slope of a line is its use as a rate . Rate The amount that a quantity of something changes over time. (Note: means “is defined as”) Examples of where a quantity changed over time would be a child’s height changing over time or profits from a business changing over time. These are examples of rates . If a child’s height changes linearly over time, then at any point in time, I can calculate his height as: Height = (Rate of Change) * (Time Interval) + Height at Time (t=0). Do you see the similarity in the equation of a straight line (y = mx + b) ? y = Height x = Time m = Rate of change b = Initial Height or Height at Time (t=0). Another familiar rate equation is to calculate Distance: Distance = Velocity * Time, or Distance = (Rate of moving) * (Time) Here is an example from my work: We have a pipe leak and the leak is getting worse every day. We know that the pipe is leaking at a rate of 1 gallon per minute. At 30 minutes,
