Question

For the direct variation equation y = 2 2/3 * x what is the constant of proportionality? Show your work.

A. 2
B. 2 2/3
C. 3
D. 2/3

Answer 1

To find the constant of proportionality in the direct variation equation y = kx, where k is the constant of proportionality, we can compare the given equation y = 2 2/3 * x to the standard form y = kx.

We can see that k = 2 2/3.

Therefore, the constant of proportionality is B. 2 2/3.
