The table:

Question

X = 30, 40, 50, 60, ( X and Y lined vertically, meaning the table is indeed vertical)

Y= 36, 48, 60, 72

Which equation represents this relationship?

Answers: y = 1.2x

y = 12x

y = x + 12

y = x + 1.2

Answer 1

The correct equation that represents this relationship is y = x + 12.

Answer 2

The table is valid in constant proportionality.

So each divided by each is Y over X = Y/X

the answer you get if you divided each one is 1.2

But what is the answer?

Answer 3

Apologies for the confusion. You are correct that in a constant proportionality relationship, the ratio of Y to X is constant. In this case, the ratio Y/X is equal to 1.2.

Therefore, the equation that represents this relationship is y = 1.2x.
