Linear Not Linear and Function

Indicate whether the quantitative relationship is a linear function.

• Linear Function

• Not a Linear Function

Diedra has a new coin bank. For the first five days, she deposits the same amount of money into the coin bank. After that, she does not deposit any more money into the bank.

Describe the rate of change (slope) of the function below.

• The rate of change is not constant.

Compare the rates of change for the two linear functions represented below. Which statement about the rates of change for the two functions is true?

• Function 2 does not have a constant rate of change, but Function 1 does.

• Function 2 has a greater rate of change than Function 1.

• Function 1 has a greater rate of change than Function 2.

• Function 1 and Function 2 have the same rate of change.

Given the table and equation below, which of the following statements is true about the functions f(x) and g(x)?

• The y-intercepts cannot be determined.

• The y-intercept of the function f(x) is equal to the y-intercept of the function g(x).

• The y-intercept of the function f(x) is less than the y-intercept of the function g(x).

• The y-intercept of the function f(x) is greater than the y-intercept of the function g(x).

A movie rental store charges a $10 membership fee plus $3.50 for each movie rented. what are the slope and y-intercept that represent this situation?

• slope = 3.50, y-intercept = -10

• slope = -10, y-intercept = 3.50

• slope = 3.50, y-intercept = 10

• slope = 6, y-intercept = 3.50

Write an equation of the line with slope of -4 and point (2, 6).

• y = -4x - 14

• y = -4x + 14

• y = -4x + 6

• y = -4x + 18

Determine the slope and y-intercept of the following equation. 7x - 2y = 10
