What is the relationship between Jayden's age and Milly's age if Jayden is 5 years younger than Milly?

Back

If Milly is 18 years old, then Jayden is 18 - 5 = 13 years old.

How do you determine the rate of change of a linear function?

Back

The rate of change is calculated as the change in y divided by the change in x (slope). For example, if Function A has a rate of change of 0.25 and Function B has a rate of change of 0.75, then Function B has a greater rate of change.

Front

What does it mean for two functions to have the same initial value?

Back

Two functions have the same initial value if they both start at the same y-value when x = 0.

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

What is the definition of a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function; a positive slope means the function is increasing, while a negative slope means it is decreasing.

Front

How can you tell if a relation is a function from a set of ordered pairs?

Back

A relation is not a function if any x-value is paired with more than one y-value.

Front

What is the initial value of a function?

Back

The initial value is the y-value of the function when x = 0.

Front

What does it mean for a function to have a greater rate of change?

Back

A function with a greater rate of change increases or decreases more steeply than another function.
