The slope of a line describes how rapidly or slowly change is occurring. Slope applies to real life, but this measurement of change is often disguised as one of the following terms:
- Rate of change
- Miles per hour
- Average rate of change
- Number of text messages per month
- Velocity
- Acceleration
- Speed
There are 3 sources that can reveal the slope of a line: the slope formula, the graph of a linear function, and the equation of a linear function.
1. Calculate Slope With a Formula
Learn these 3 easy steps of the slope formula.
2. How to Find the Slope of a Line With a Graph
How can you verify the slope of a line just by looking at its graph? Think rise over run.
3. Graph Line - Learn to Graph Line in Slope Intercept Form
Whenever a linear function is written in slope-intercept form, the slope is obvious. Practice identifying the slope of a linear equation.
4. Slope Intercept Form
What do you do when a linear equation is not expressed in the slope-friendly slope-intercept form? Solve to transform the equation into slope-intercept form.
5. Slope intercept Form Worksheet
Here's a linear equation:
12y - 12 = 60x
What is the slope? Practice writing this equation (and others) in slope-intercept form.
