Answer: h = 9n
Explanation:
Probe with the numbers in the table whether they represent a direct variation.
In a direct direction the ratio of the variable is a constant.
This is: y / x = constant.
Indeed, the numbers of the table represent a direct variation, which you prove in this way:
- 18 / 2 = 9
- 27 / 3 = 9
- 36 / 4 = 9
Therefore, the ratio is y / x = 9
From there, you obtain the rule, h / n = 9 ⇒ h = 9n, which is the first choice.
