Proportional Graphs!

Front

What is a proportional graph?

Back

A proportional graph is a graph that represents a constant ratio between two variables, typically shown as a straight line that passes through the origin.

Front

Does a proportional graph always pass through the origin?

Back

Yes, a proportional graph always passes through the origin (0,0).

Front

What shape does a proportional graph have?

Back

A proportional graph has a straight line shape.

Front

If a graph is curvy, can it still be proportional?

Back

No, if a graph is curvy, it is not proportional, even if it passes through the origin.

Front

How can you tell if a graph is proportional?

Back

You can tell if a graph is proportional if it has a straight line and passes through the origin.

Front

What does it mean if a graph does not pass through the origin?

Back

If a graph does not pass through the origin, it is not proportional.

Front

Can a proportional graph have negative values?

Back

Yes, a proportional graph can have negative values as long as it maintains a constant ratio.

Front

What is the relationship between the x and y values in a proportional graph?

Back

In a proportional graph, the ratio of y to x is constant.

Front

What is an example of a proportional relationship in real life?

Back

An example of a proportional relationship is the relationship between distance and time when traveling at a constant speed.

Front

What happens to the graph of a proportional relationship if the ratio changes?

Back

If the ratio changes, the graph will no longer be a straight line through the origin.
