1. Graphing Data on the Coordinate Plane
1-9

2. Two number lines that intersect at right angles form a coordinate plane.
The horizontal axis is the x-axis and the vertical axis is the y-axis.
The axes intersect at the origin and divide the coordinate plane into four quadrants

3. What are the coordinates

5. What quadrant
(2,3)
(-1,4)
(3,-4)
(-1,-1)

6. An ordered pair of number identifies the location of a point
These number are the coordinates of the point on the graph
In the ordered pair (4,2), the first number 4 is called the x-coordinate (abscissa). The second number 2 in the ordered pair is called the y-coordinate (ordinate).

7. A scatter plot is the graph that relates two group of data.
A Trend line on a scatter plot shows a correlation more clearly

8. Positive correlation - both sets increase together
Negative correlation - one set increases while the other decrease
No correlation – data is not related

9. Name the correlation
