Answer:
C
Step-by-step explanation:
The question asks for a 0.3 constant of proportionality between 'x' and 'y'.
So, if you multiplied 0.3 to the number in 'x', you would get the number in 'y'.
By process of elimination, we can find that in A, 0.3 * 6 is not 2 and it's the same for all the other numbers in the table.
For B, 3*0.3 is not 1.8 and 0.3 multiplied by the other numbers in B do not match the number in y.
The only answer that matches is C, 4*0.3 is 1.2, 8*0.3 is 2.4, and 13*0.3 is 3.9.
So, the answer is C.
