## Chapter 6 Lesson 3 – Slope Of A Line

Lesson 3 is about a super important topic when learning about lines in algebra- the topic is “slope”. The slope of a line is the angle of the line and we really need to understand the slope to graph lines and find the equation of a line. By the way I have been talking about graphing and finding the equation of lines- these “line” equations have a mathematical name called “linear equations”. So this chapter is really all about linear equations and slope.

Things to focus on in this lesson:

• the definition of slope

• the rise over the run

• how to find the slope given two points

**Pop quiz:** True or False – A variable represents a number?

### Well done you finished lesson 3 on slope. You should be able to:

* define the slope

* find the slope given two points

* know the difference between negative and positive slopes

Now that you understand the slope we can continue to learn more about graphing lines
