A1 Video 3-1 Graphing Linear Patterns

The key to this lesson is recognizing that we have a ________ increase or ________ decrease situation. (Fill in the blanks with the same word.)

• variable

• constant

• blue block

• brown blocks

In the pool example, what does the variable x represent?

• The number of hours since filling started.

• The amount of water in gallons.

• The width of the pool in meters.

• The depth of the pool in feet.

How much does the water level rise every hour in Sharon's pool?

• 5 inches

• 4 inches

• 3 inches

• 2 inches

What is the initial depth of the water in the pool before filling?

• 12 inches

• 4 feet

• 5 inches

• 1 foot

What is the equation used to model the pool's water depth over time?

• y = 4x + 12

• y = 5x + 15

• y = 3x + 10

• y = 2x + 8
