Comparing Linear Functions

How can you interpret the y-intercept of a linear function?

• The y-intercept represents the average rate of change of the linear function.

• The y-intercept represents the slope of the linear function.

• The y-intercept represents the value of y when x is equal to zero.

• The y-intercept represents the value of x when y is equal to zero.

Which function has a greater rate of change?

• The rate of change is the same for both functions

• Function 1 has a greater rate of change

• Function 2 has a greater rate of change

• There is not enough information to determine which function has a greater rate of change.

Compare the two linear functions listed below and determine which has a greater slope.

• Function 1 because the slope is 12
• Function 2 because the slope is 1
• Function 1 because the slope is 1/12
• They are equal
