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 identify a proportional relationship in a table?

Back

You can identify a proportional relationship in a table by checking if the ratio of y to x is constant for all pairs of values.

Front

What is the constant of proportionality in the equation y = kx?

Back

The constant of proportionality is the value 'k' that represents the ratio of y to x.

Front

If y = 14x, what is the constant of proportionality?

Back

14

Front

What does it mean if a graph is proportional?

Back

If a graph is proportional, it passes through the origin (0,0) and has a straight line.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be written as y = kx, where k is the constant of proportionality.

Front

Is the table below proportional? (x: 1, y: 2; x: 2, y: 4; x: 3, y: 6)

Back

Yes, the table is proportional because the ratio of y to x is constant (2:1).

Front

What is the ratio of y to x in a proportional relationship?

Back

The ratio of y to x is constant and equal to the constant of proportionality.

Front

If a table shows (x: 1, y: 3; x: 2, y: 5), is it proportional?

Back

No, it is not proportional because the ratio of y to x is not constant.

Front

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

Back

A non-proportional relationship does not have a constant ratio between the two quantities.
