Objectives:
- I can write the linear equation of a graph given two points on the line.
What is a linear equation?
A linear equation has two variables that when graphed it creates a straight line.
You have previously learned how to write a linear equation given a graph. If you recall, you needed the slope and y-intercept. You found the slope by performing rise over run. In this case, you will also need the slope and y-intercept but instead of performing rise over run, you will use the slope formula to find the slope between two points.

In order to write a linear equation, we need to know the...
Now, let's look at an example! Remember, we need two pieces of information: (1) Slope and (2) y-intercept.
Let's look at one more example when we have two points with the same y-coordinate.
