The value of y varies directly with the value of x. Which function represents the relationship between x and y if y=7/3 when x=21?

Step-by-step explanation:

Equation of a direct equation is given as , where k is the constant of proportionality.

Let's find k given that y = ⁷/3 when x = 21.

Plug in the values of x and y into to find k.

Thus:

Divide both sides by 21

Substitute k = ¹/21 into .

✅Thus, the function represents the relationship between x and y would be:
