Linear Modeling (Scenarios, Tables & Graphs)

Lilian invested $20 in her store. She earns $3 for every 4 days that her store is open.

What is the initial value?

• $20

• $0

• $3

• $4

Lilian invested $20 in her store. She earns $3 for every 4 days that her store is open.

What is the rate of change?

• $20

• $3 / 4 days

• $4 / 3 days

• $3

Patrick gets a $50 fine for parking in a no parking zone. He gets an additional fine of $25 per day for each day that he does not move his car.

• $50

• $125

• $150

• $175

Patrick gets a $50 fine for parking in a no parking zone. He gets an additional fine of $25 per day for each day that he does not move his car.

What is the initial value?

• $50

• $25

• $75

• $100

What does 1000 represent in the context of the problem?

• How much the loan is originally for

• How much is paid off each week

• How much is owed after 3 weeks

• How much is owed after 7 weeks.

Why is the slope negative in this problem?

• Because the laptop is increasing in value

• Because the amount of the loan decreases as you pay it off

• Because the amount of the loan increases as you pay it off

• Because the number of laptops you own decreases

What does 30 represent in this scenario?

• How much you have before you start saving money

• How much you save each week

• How many weeks you are going to save for

• How much you have saved after 5 weeks

How much money are you saving each week?

• $5

• $10

• $20

• $30

Which equation matches this graph?

• $y=5x+30$

• $y=-5x+30$

• $y=10x+30$

• $y=-10x-30$

How much money is saved after 7 weeks? 

• $65

• $50

• $60

• $70
