Do Now. You have 5 minutes. 1. Jenny has saved $25 to buy a new pair of shoes. Each month, she saves $5 towards the shoes. Which expression could be used to find the total amount saved after m months?

a. 5mb. 25 + 5mc. 25m + 5d. 25m + 5m

2. The cost to rent a laptop from Best Buy is $20 plus $10 per hour. Write an expression to find the total cost for any number of hours.

Today’s Objective

SWBAT graph ordered pairs on the coordinate plane.

Introduction to Graphing: terms for those in the know1. When graphing points: you can locate a point by using a

coordinate system similar to the grid of a park (or

Washington, DC) – put up map of Washington, DC.

2. The grid is called: Coordinate plane

3. Y-axis: the y-axis the vertical number line

4. X-axis: the horizontal number line

5. Quadrants: four sections of the coordinate plane

6. Origin: the point of intersection of the two number lines

Intro to Graphing: Ordered Pairs

• You can graph any point on the coordinate plane by using an ordered pair. (3,2)• The first number in the ordered pair is the x-

coordinate.• The second number is the y-coordinate. • Steps to name an ordered pair: 1. Start at the origin2. Move right to find the x-coordinate3. Move up to find the y-coordinate

Guided Practice: White Boards

1. Draw y-axis2. Draw x-axis3. Put a star at the origin4. Number -3 to 3 on the x-axis5. Number -3 to 3 on the y-axis6. Graph the ordered pair (3, 2)7. Graph the ordered pair (-2, 1)8. Graph the ordered pair (1, -2)9. Graph the ordered pair (-1, -3)

Independent Practice• Pg. 278: 1-11• Computer users: first take the Review Quiz on

Brain Pop; after you have completed this, take the Graded Quiz. Review your answers and write down how many you got correct.

Tonight’s Homework: • Pg. 279: 12 – 33 (odds only) – for the problems that ask you to

graph each ordered pair on a coordinate plane, you will need to draw your own coordinate plane.

Exit Ticket:

1. Draw a coordinate plane.

a. Label the x-axisb. Label the y-axisc. Label the origind. Graph the point
