What does the x-axis represent in a graph?

Back

The x-axis is the horizontal number line on a graph.

Front

What does the y-axis represent in a graph?

Back

The y-axis is the vertical number line on a graph.

Front

How can you identify a proportional graph?

Back

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

Front

What is the origin in a coordinate plane?

Back

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

Front

What is an example of a proportional relationship?

Back

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

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per one unit.

Front

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

Back

If a graph does not go through the origin, it indicates a non-proportional relationship.

Front

What is a table of values in relation to proportional relationships?

Back

A table of values shows pairs of numbers that represent the quantities in a proportional relationship.
