1. Chapter 9: Algebra: Patterns and Graphing
MAFS.5.MD.2.2; MAFS.5.G.1.1; MAFS.5.OA.2.3

2. Vocabulary
interval the fixed distance between any two consecutive numbers on the scale of a graph
Ex: Pattern of the graph is by 5’s or 2’s
line graph a graph that uses line segments to show how data changes over time
ordered pair the pair of numbers used to locate points on a grid
Ex: (5,2)
origin the point where the x-axis and the y-axis intersect; (0, 0)
scale a series of numbers placed at fixed distances on the graph that help label it
Ex: the graph begins at 0 and ends at 60
x-axis the horizontal number line on a coordinate plane
x-coordinate the first number in an ordered pair, which tells the distance to move right or left from (0, 0)
y-axis the vertical number line on a coordinate plane
y-coordinate the second number in an ordered pair, which tells the distance to move up or down from (0, 0)

3. Lesson 9.1 Line Plots
Line Plot - a graph that shows frequency of data along a number line. It is best to use a line plot when comparing fewer than 25 numbers. It is a quick, simple way to organize data.
Ex.
Plot the information on the line plot.

4. Lesson 9.1 Create Your Own Line Plot1. 2.

5. Lesson 9.2 Ordered Pairs You name coordinates by using:
1. Plot A (3,5)
2. Plot B (0,8)
3. Plot C (9,0)

6. 9.2 Ordered Pairs cont’d
Point Z is 4 units away from the origin on the x‐axis. What could be the coordinates of point Z?
2. Point M is 5 units away from the origin along the x‐axis, and 6 units away along the y‐axis. What could be the coordinates of point M?

7. 9.2 Cont’d 3.

8. Lesson 9.5 Numerical Patterns
Ex: Find the pattern and fill in the table: 2.

9. Lesson 9.6 Extend and Compare Patterns2.

10. Lesson 9.7 Graph and Analyze Relationships2.

11. Chapter 9 Review for Test
1. Point S is located at (8,8).
Point T is located 2 units below S.
Plot Point S and Point T.
2. The location of the Boosterthon Pep Rally is show on the coordinate plane. Mrs. Daniels’ left her classroom, went 3 units down and 3 units left, and arrived at the Pep Rally.
Where is Mrs. Ransom’s classroom? 3.
How many recipes called for 2 cups of milk? _____ 4.
Pep Rally
