How can you identify a function from a table?

Back

A table represents a function if each input (x-value) corresponds to only one output (y-value).

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be expressed in the form y = kx, where k is a constant.

Front

How do you determine if a graph represents a proportional relationship?

Back

A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0).

Front

What does the slope of a line represent in a proportional relationship?

Back

The slope of a line in a proportional relationship represents the constant of proportionality (k).

Front

What is the difference between a function and a non-function?

Back

A function has one output for each input, while a non-function may have multiple outputs for a single input.

Front

What is an example of a function?

Back

An example of a function is the equation y = 3x, where for every x, there is one corresponding y.

Front

What is a non-example of a function?

Back

An example of a non-function is the relation {(1,2), (1,3)}, where the input 1 has two different outputs.

How do you find the hourly rate of pay from a total amount earned?

Back

To find the hourly rate, divide the total amount earned by the number of hours worked.
