The constant of proportionality is 5.

Front

How do you identify the constant of proportionality from a graph?

Back

The constant of proportionality is the slope of the line in a graph of y vs. x.

Front

What is the relationship between y and x in a proportional relationship?

Back

y is directly proportional to x, meaning as x increases, y increases at a constant rate.
