Writing and interpreting linear functions

What is the linear parent function?

• y = x 
• y = mx + b 
• f(x) = 2x 
• f(x)  = y 

Find the rule for the table.

• y = 3x + 6

• y = 6x + 6

• y = 9x + 2

• y = 3x + 3

The table shows the cost of a pizza, P(t), based on the number of toppings, t. Write a linear function for P(t).

• P(t) = 3t + 17.5

• P(t) = 2t +11.5

• P(t) = 3.5t + 9

• P(t) = 2.5t + 10

Write the equation for the relationship shown in the table.

• y = 1/4x

• y = 4x

• y = x + 4

• y = x - 4

What is the equation of the line?

• y = 2x + 2
• y = -2x -2
• y = 2x + 0 
• y = -2x + 2

Write an equation that describes the function

• y=x-7

• y=x+7

• y=x*4

• y=x-4

The table represents some points on the graph of a linear function. Which function represents the same relationship?

• h(x) = -3x - 10.5

• h(x) = -x - 3.5

• h(x) = 3x - 10.5

• h(x) = x - 3.5

The table shows the number of customers each hour for an online sale.

Which function best models the data in the table?

• f(x) = 296 - 41x

• f(x) = 337 - 41x

• f(x) = 317 - 38x

• f(x) = 296 - 38x

The table represents some points on the graph of linear function f. Which function represents f ?
