Answer:

B

Step-by-step explanation:

Since x varies directly as y, the ratio of x to y remains the same. Let the value of x when y=4 be a. Then we have

\dfrac {7 \frac12} {10} = \dfrac a4

We can cross multiply to get that

10a = 30, \text{so } \boxed{a=3}

⅖ is less than ⅘ so it would come before c

6/5 is more than 1 so it wouldn’t be on that number line.
