Question

Find the rule for (3,1) (6,2) (9,3) (12,4) (15,5)​

Answer 1

Answer:

y = $\frac{1}{3}$ x

Step-by-step explanation:

Compare the values of y with the values of x for each ordered pair

x  y

3  1 → y = 3 ÷ 3

6  2 → y = 6 ÷ 3

9  3 → y = 9 ÷ 3 = 3

12 4 → y = 12 ÷ 3 = 4

15 5 → y = 15 ÷ 3 = 5

The y value in each case is the x value divided by 3

Hence rule is

y = $\frac{1}{3}$ x
