Linear Versus Nonlinear Functions Graphs

Liam, Jackson, and Zoe are selling bird seed for a school fundraiser. The table they have shows the cost (y) in relation to the number of pounds (x) of bird seed they sell. What is the missing y value that would make this a linear function?

• 2.80

• 1.40

• 4.20

• 3.90

Arjun is trying to predict the amount of money he will earn based on the number of hours he works. He has created a table of values to represent this. Which equation matches Arjun's table?

• y = 10x + 5

• y = 5x + 10

• y = 5x + 20

• y = x + 10
