Question

Which equation could have been used to create this function table?












A.

y = 3x








B.

y = x + 3








C.

y = 4x








D.

y = x + 2

Answer 1

A) y=3x
You can plug in the given values (inputs) of x to see if it creates the number in y (output). 
3*1=3 
3*2=6
3*3=9
3*4=12
3*5=15
3*6=18

All these values are true, therefore the equation y=3x is the correct answer.
