2/5

Front

What does it mean if the Constant of Proportionality is greater than 1?

Back

It means that as x increases, y increases at a rate faster than x.

What does it mean if the Constant of Proportionality is less than 1?

Back

It means that as x increases, y increases at a rate slower than x.

Front

What is the relationship between the Constant of Proportionality and slope in a graph?

Back

The Constant of Proportionality is the slope of the line in a graph of y versus x.

Front

If the Constant of Proportionality is 0, what does that indicate?

Back

It indicates that there is no relationship between x and y; y is always 0 regardless of x.

How can you find the Constant of Proportionality from a table of values?

Back

Divide the y-value by the corresponding x-value for any pair of values.
