In a direct variation, the constant of proportionality is -3.

which of the following would be its equation?

y = x - 3
-3y = x
y = -3x
-3 = xy

The equation is .

Step-by-step explanation:

When we say that a variable varies directly as another variable, or is directly proportionate to another variable, we mean that the variable changes with the same ratio as the other variable increases.

This kind of correlation can be represented as a linear function that passes through the origin, the equation of which is of the form . The two variables we are considering are x and y, while k is called the constant of proportionality.

We know the constant of proportionality k = -3, applying the above definition we get that the equation is .

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

168

step-by-step explanation:

i am pretty sure that the answer is 168
