Front

What is a proportional relationship?

Back

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

Front

What is a non-proportional relationship?

Back

A relationship where the ratio of one quantity to the other is not constant.

Front

How do you determine if a table is proportional?

Back

If the ratios of the quantities in the table are equivalent, the table is proportional.

Front

What is a unit rate?

Back

A comparison of two quantities where the denominator is always 1 unit.

Front

What does the slope of a proportional graph represent?

Back

The constant ratio of the change in the y-value to the change in the x-value.

Front

What is the equation of a proportional relationship?

Back

y = kx, where k is the constant of proportionality.

Front

How can you identify a proportional graph?

Back

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

Front

What is the constant of proportionality?

Back

The constant ratio in a proportional relationship, often represented by 'k'.

Front

If a table shows the values (2,4), (3,6), (4,8), is it proportional?

Back

Yes, because the ratios (y/x) are all equal to 2.

Front

What is the meaning of coordinate (x,y)?

Back

A pair of values that represent a point on a graph, where 'x' is the horizontal position and 'y' is the vertical position.
