**distance between two points**. Basically, it's like the

**Pythagorean Theory**but more easier to use if the distance you are trying to find is in the graph. The formula to get the distance between two points looks like this:

**Recall:**A point on a graph is denoted by the coordinates

**(x,y)**

If **AB** is 5 spaces high and **BC** is 7 spaces long, you would use the **Pythagorean Theorem** to get **AC**, right? Your work would look somewhat like this: But if you used the **distance formula**, you wouldn't need the 'spaces' because using this formula would give you the sides of all the area all in one equation.

**1 **is **(-4, -1)** and **2** is **(3, 4)**

It doesn't matter if you switched the **1** as **(3, 4)** and **2** as **(-4, -1)**.

Well, that's what we learned today. It's kind of confusing at first and almost everybody has this "wha..?" face when Ms. Armstrong was explaining it to us...

oh yeah ...** Kriszelle**, your doing it next...
