Answer:

the answer is B

Step-by-step explanation:

because if you substitute the x column on the equation so for example 3 x 1 =3 and 3 x 3 = 9 and 3 x 4 = 12 and 3 x 7 = 21 so y = 3x is represented

The answer is B because A just isn't correct its backwards for starters and the wrong numbers, C is wrong because its just doubles, and D is wrong because 4 x 3 isnt 9 and 6 x 3 isnt 12 and 7 x 3 isnt 18.

B is the only one that works
