What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant.

Front

How can you tell if a table of values is proportional?

Back

A table of values is proportional if the ratios of corresponding values are equal.

Front

What does it mean for a graph to be proportional?

Back

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

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be expressed in the form y = kx, where k is the constant of proportionality.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities.

Front

What does a non-proportional graph look like?

Back

A non-proportional graph does not pass through the origin and may be curved or not a straight line.

Front

If a table shows the values (1,3), (2,6), (3,9), is it proportional?

Back

Yes, it is proportional because the ratio of y to x is constant (y/x = 3).

Front

If a graph passes through (0,0) and (2,4), is it proportional?

Back

Yes, it is proportional because it is a straight line that passes through the origin.

Front

What is the slope of a proportional relationship?

Back

The slope of a proportional relationship is equal to the constant of proportionality (k).

Front

How do you write an equation from a proportional table?

Back

Identify the constant ratio (k) and use the form y = kx to write the equation.
