Proportional Graph

What is a proportional graph?

Back

A proportional graph is a graph that shows a constant ratio between two variables, meaning that as one variable increases, the other variable increases at a consistent rate.

What does the ordered pair (0,0) represent on a graph?

Back

The ordered pair (0,0) represents the origin on a graph, where the x-axis and y-axis intersect.

What does it mean if a graph is non-proportional?

Back

A non-proportional graph does not show a constant ratio between the two variables, meaning the relationship between them is not consistent.

What is the formula for a proportional relationship?

What is the significance of the slope in a proportional graph?

Back

In a proportional graph, the slope represents the constant of proportionality, indicating how much y changes for a unit change in x.

Front

How can you tell if a graph represents a proportional relationship?

Back

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

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant ratio and pass through the origin, while non-proportional relationships do not have a constant ratio and may not pass through the origin.

What does the term 'dependent variable' mean?

Back

The dependent variable is the variable that depends on the value of another variable, typically represented on the y-axis.
