Linear FunctionsIf 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! Example 1
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. Example 2
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. Example 3
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!
