Jade Ho · Answer 1

y DOES NOT vary directly with x

Step-by-step explanation:

If variation is direct, the ratio of y to x is a constant. Here, we have ...

11/7 ≠ 13/8

so variation is not direct.

___

It appears that y = 2x-3, rather than y = kx for some k. The added constant (-3) means variation is not direct.
