Constant of Proportionality (Tables)

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant factor (k) that relates two proportional quantities, expressed in the equation y = kx.

Front

How can you determine if a table is proportional?

Back

A table is proportional if the ratio of y to x is constant for all pairs of values.

Front

What does a proportional relationship look like on a graph?

Back

A proportional relationship is represented by a straight line that passes through the origin (0,0).

Front

If y = 2x, what is the constant of proportionality?

Back

The constant of proportionality is 2.

Front

What is the equation for a proportional relationship?

Back

The equation for a proportional relationship is y = kx, where k is the constant of proportionality.

Front

If the constant of proportionality is 1/3, what is the relationship between x and y?

Back

The relationship is y = 1/3 x.

Front

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

Back

A table is non-proportional if the ratios of y to x are not constant.

Front

How do you find the constant of proportionality from a table?

Back

To find the constant of proportionality, divide the y-value by the corresponding x-value for any pair of values.

Front

If y = 4x, what is the value of y when x = 3?

Back

When x = 3, y = 4 * 3 = 12.

Front

What is the constant of proportionality in the equation y = 5x?

Back

The constant of proportionality is 5.
