If m varies directly with x, then that means that you have to find the slope. To make it easier, m = y-variable, and x = x-variable.

Because you are trying to find your constant of variation (another word for slope, rate of change, etc.), the change of y over the change of x is your equation. in other words, divide your m variable by x.

When m = 60 and x = 6, you can set it up. 60 / 6 = k; and k = 10 when solved. Since 10 is not one of the answer choices listed in your answer key, I believe that your answer is NONE OF THE ABOVE.


I hoped this helped you.

None of the above (e) is the answer. This problem can be easily solved with the formula m/x=k. Specifically for this problem, the equation would be 60/6=k. Basic division tells us that k=10, which is not one of the choices you had to choose from. Therefore, the answer is e.
