Answer: Multiply by 3 in everyone

Step-by-step explanation: 4 times 3 is 12    5 times 3 is 15            6 times 3 is 18 and       7  times 3 is 21

Answer:

It will probably be y = 3(x)

so let's take the first example

x = 4

so use the rule

y = 3(x)

y = 3(4)

y = 3 x 4

y = 12

that's how y became 12.

So use the rule : y = 3(x)
