If you studied the writing equations unit, you learned how to write equations given two points and given slope and a point.
If you did well with that unit, then studying linear functions will be a great review. If you had trouble with that unit, then you may want to go back and review the following concepts before starting this lesson:
Let's quickly review ordered pairs and function notation before moving on!
Ok.. now that you know how to write an ordered pair from function notation, let's look at an example!
Ok, that was pretty easy, right? Yes...now do you see how Math has that spiral effect? You already knew this skill, but it's coming back in a different format!
Next we are going to take it one step further and find the slope of the graph for a linear function. Take a look at this example.
Now, let's take it one step further. We are going to find an equation for a linear function. Notice how we use steps from example 2 to start this problem.
Is it all coming back to you now? Although this does not complete this lesson, we are going to stop and practice a few problems before moving on!
