1. Section 1-9: Graphing Data on the Coordinate Plane

2. Cartesian Plane: (Coordinate Plane)y
II I
ORIGIN x
III IV
QUADRANTS
AXES

3. Ordered Pair (x, y) The coordinates of a point
Ordered Pair (x, y) The coordinates of a point. (Horizontal movement, Vertical movement) ***It takes 2 values to make ONE POINT. Plot (2, 3) WRONG CORRECT

5. Scatter Plot:
A graph of ordered pairs that represent 2 different sets of data.
i.e.
You could plot how many hours you worked at a job for a week and the paycheck amount you received for the hours you worked. You could see if there was a relationship between your 2 sets of data.

6. Positive Correlation: When your data graphs in a POSITIVE slope.

7. Negative Correlation: When your data graphs in a NEGATIVE slope.

8. No Correlation: When there appears to be no significantly positive nor negative slope forming. (your data is unrelated to each other)
