Small Review not in the Notes...
1) What are the two types of geometry we talked about yesterday?
AN EASY WAY TO REMEMBER THIS IS...
2) Which type had points that had size and shape?
3) There are two points on a number line that are 15 units apart. One number is ­2. What are the two other possible numbers?

Points are set ordered pairs and lines are the set
of ordered pairs that satisfy AX + BY = C
a location in the Cartesian Plane
An ordered Pair is ____________________________________

a as the x coordinate and b as the y coordinate.
The point (a , b) has
moving "b" units on the y ­ axis
You plot the point (a, b) by Remember where your points go!
