1. To Start:
Simplify the following: -5(2)(-4) -4(-3)(6) -6(2)(-1)
= 40
= 72
= 12

2. Chapter 1: Algebraic Expressions and Integers
Section 1-10: The Coordinate Plane

3. II I III IV The Coordinate Plane
The x and y axis divide the coordinate plane into 4 quadrants. The origin is where the x and y axis intersect. II I
III IV

4. Ordered Pair
An Ordered Pair gives the coordinates and location of a point. (-5,-4)
The x-coordinate
The y-coordinate

5. Graphing Points Graph the following points: A (3,5) B (-3,-4) C (4,-2)
D (-1,2) D C B

6. Graphing Points – You Try!!
Graph the following points:
A (2,4)
B (-2,-3)
C (0,-2)
D (-1,5) D A C B

7. Finding Coordinates (2,2) (-1,-2) (2,-3) (-3,1)
List the coordinates for the following points: A B C D
(2,2) A D
(-1,-2)
(2,-3) B
(-3,1) C

8. Finding Coordinates – You Try!!
List the coordinates for the following points: A B C D A B
(4,4)
(-1,3)
(4,-4) D
(-3,-2) C

9. Name the Coordinates (-5,3) (3,6) (-8,-6) (9,-8)
Write the coordinates of each point: A point that is 5 units left and 3 units above the x-axis: A point that is 3 units right and 6 units above the x-axis: A point that is 8 units left and 6 units below the x-axis: A point that is 9 units right and 8 units below the x-axis:
(-5,3)
(3,6)
(-8,-6)
(9,-8)
