Writing Equations from Tables, Graphs and Situations

Front

What is a proportional relationship?

Back

A proportional relationship is one in which two quantities maintain a constant ratio. If one quantity increases, the other increases at a consistent rate.

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

Back

A table represents a proportional relationship if the ratio of the values in one column to the values in another column is constant.

What does the slope of a line represent in a real-world context?

Back

The slope represents the rate of change between two quantities. For example, in a water filling scenario, it indicates how fast the water level rises.

What does it mean if a relationship is nonproportional?

Back

A nonproportional relationship does not maintain a constant ratio between two quantities; the rate of change varies.
