Constant of Proportionality, y=kx

Front

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

Back

The constant of proportionality (k) is the ratio of y to x, which remains constant for all values of x and y in a proportional relationship.

Front

Which equation represents a proportional relationship?

Back

y = 7x

Front

What is a proportional relationship?

Back

A proportional relationship is one where two quantities maintain a constant ratio or rate.

Front

What does it mean if a graph is proportional?

Back

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

Front

How can you identify a proportional relationship from a table of values?

Back

If the ratio of y to x is constant for all pairs of values, then the relationship is proportional.

Front

What is the unit rate in a proportional relationship?

Back

The unit rate is the constant of proportionality expressed as a ratio of y to 1 unit of x.

Front

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

Back

The constant of proportionality is 3.

Front

What does the slope of a line represent in a proportional relationship?

Back

The slope represents the constant of proportionality.

Front

If a table shows (1, 2), (2, 4), (3, 6), is this a proportional relationship?

Back

Yes, the constant of proportionality is 2.

Front

What is the significance of the point (0,0) in a proportional graph?

Back

It indicates that when x is 0, y is also 0, confirming the relationship is proportional.
