Which equation represents a proportional relationship between the x and y values? a) y = 2 b) y = 1 4 x + 1 c) y = x − 4 d) y = −2x

y = -2x

Step-by-step explanation:

Variation has to do with determining the relationship between two or more variables.

We have different types of variables which includes the direct, inverse, partial and joint variation.

In direct variation, increase or decrease in a variable leads to increase or decrease in the other variable. For example, given two variables x and y.

If y is directly proportional to x, it is written as y = kx where k is a constant of proportionality.

In the question above, the only function that represents a proportional relationship is y = -2x where -2 serves as the proportionality constant.

The function is a direct variation.

i can you with this question sweetie!

step-by-step explanation:

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
