Q2-1.1a Graphing Data on the coordinate plane

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

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

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

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

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

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)

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

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

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

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)

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

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