Question

Which is the constant of variation, k, if y=kx, and y=10 when x=15?

A. 2/3

B. 3/2

C. 10

D. 15

Answer 1

The constant of variation, k, when y = 10 and x = 15 in the equation y = kx, is 2/3.

Step-by-step explanation:

The student is asking about the constant of variation (k) in the direct variation equation y = kx. Given that y = 10 when x = 15, we can find k by rearranging the equation to solve for k, which is k = y/x. Plugging in the values gives us k = 10/15, which simplifies to 2/3. Therefore, the constant of variation, k, is 2/3.

Answer 2

A. 2/3

Step-by-step explanation:

If your equation is y=kx then you just fill in the variables that you have.

`y=kx\\10=15k\\k=2/3`
