Proprtional Relationships Test

Front

What is a proportional relationship?

Back

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

Front

How do you identify a proportional relationship from a graph?

Back

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

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant ratio (k) between two proportional quantities, often expressed as y = kx.

Front

If y = 3x, what is the constant of proportionality?

Back

The constant of proportionality is k = 3.

Front

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

Back

A table represents a proportional relationship if the ratios of y to x are the same for all pairs of values.

Front

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

Back

If a graph does not pass through the origin, it indicates that the relationship is not proportional.

Front

If Mrs. C can tie 300 bows in 5 hours, how many bows can she tie in 1 hour?

Back

She can tie 60 bows in 1 hour.

Front

What is the equation for a proportional relationship if y varies directly with x?

Back

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

Front

If the constant of proportionality is k = 4, what is y when x = 5?

Back

y = 4 * 5 = 20.

Front

What is the formula to find the constant of proportionality from a table?

Back

k = y/x for any pair of values (x, y) in the table.
