Graph-Proportional or Non proportional?

Front

What does it mean if a graph is proportional?

Back

A graph is proportional if it shows a constant ratio between two quantities, meaning as one quantity increases, the other increases at a consistent rate.

Front

What does it mean if a graph is non proportional?

Back

A graph is non proportional if it does not show a constant ratio between two quantities, meaning the relationship between the quantities changes.

Front

Can you give an example of a proportional graph?

Back

An example of a proportional graph is the relationship between the number of apples and their total cost if each apple costs the same amount.

Front

Can you give an example of a non proportional graph?

Back

An example of a non proportional graph is the relationship between the number of hours worked and total pay if the pay rate changes after a certain number of hours.

Front

What is a constant ratio?

Back

A constant ratio is a fixed relationship between two quantities, where one quantity is always a specific multiple of the other.

Front

How can you tell if a graph is proportional?

Back

You can tell if a graph is proportional by checking if it passes through the origin (0,0) and if it forms a straight line.

Front

What is the origin in a graph?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0,0).

Front

What does a straight line in a graph indicate?

Back

A straight line in a graph indicates a consistent relationship between the two variables, which can suggest proportionality.

Front

What is an example of a non proportional relationship?

Back

An example of a non proportional relationship is the distance traveled by a car when the speed changes; the distance does not increase at a constant rate.

Front

What is the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, indicating the value of y when x is zero.
