Question

Find the constant of proportionality (r). Using the value for r, enter an equation in the form of y = rx. Write the values of r in the form of a whole number or fraction.

A. r = 5/6, y = 5/6 x
B. r = 6/5, y = 6/5 x
C. r = 5, y = 5 x
D. r = 6, y = 6 x

Answer 1

The constant of proportionality (r) for the given equation y = rx is 5/6. The correct equation is y = 5/6x.

Step-by-step explanation:

The constant of proportionality (r) can be found by comparing the ratio between the values of the dependent variable (y) and the independent variable (x). In this case, the correct equation is y = 5/6x, which means that for every 6 units increase in x, y increases by 5 units. Therefore, the correct answer is A. r = 5/6, y = 5/6 x.
