1. Q2-1.1a Graphing Data on the coordinate plane

2. Graph each number on a number line
a) b) c) d) -1.2

3. Graph each number on a number line
a) b) c) d) 4.9

4. The Coordinate plane- A horizontal number line (x –axis)
A vertical number line ( y- axis)
Put them together at zero ( origin).

5. ( - 2 , 4 ) X – Coordinate Y – Coordinate
Ordered Pair – Tells us where the point is on the coordinate plane
( - 2 , 4 )
X – Coordinate
Y – Coordinate

6. ( - 2 , 4 )
Left 2 on
X-axis
Up 4 on
Y – axis

8. It breaks the grid into 4 QUADRANTS
Quadrant I - x and y values are both positive ex. ( 4, 5)
Quadrant II - x value negative, y value is positive ex. ( -3 , 4)
Quadrant III - x and y values are both negative ex. ( -4, -6)
Quadrant IV – x value is positive, y value is negative ex. ( 5, -2)

9. Put these ordered
Pairs in the correct
quadrant
( + ,- )
( - , - )
( +, +)
( - , +)

10. Find the coordinates of :
Lunchroom = ( , )
Bathroom = ( , )
Office = ( , )
C-1 = ( , )
C-202 = ( , )

11. Ex.
Graph the points:
A ( 2,3)
B (-1,2)
C( -3, -3)
D (0, -2) A B D C

12. Graph the following coordinates
B ( 8 , 1)
C ( 0, 4)
D ( -1, 1)
E ( -4, -2)
F ( -3 , -6)
G ( 5, -2)
H ( 7, 0)
I ( 8, -4)

13. Ex. Find the missing Coordinates D ( ) -3 , 2 A(5,2) C ( -3, -4)
B( , ) 5 -4

14. Ex 2.
W ( -4 , 7 )
R ( )
6 , 7
S ( 6 , -8 )
P ( )
-4 , -8
