The value of y varies directly with the value of x, and y = 12 when x = 4.
which equations represent the relationship between y and x?
choose exactly two answers that are correct.
a. y/x=3
b. xy=3
c. x=3y
d. y=3x

So we want to see which equation connects x and y in a way that when x=4 then y=12 and there are two correct answers. We can see that y is 3 times greater than x so lets write that as an equation: y=3x. We see that this corresponds to answer D. We can also rewrite that as y/x=3 and that corresponds with answer A. Those are the two correct answers.
