Which equation describes a relationship that is directly proportional? y= 9 y= 3x y= .20 y= x + 4

B.

Step-by-step explanation:

We are asked to find the equation that describes a directly proportional relationship.

We know that two proportional quantities are in form , where, y is proportional to x and k is the constant of proportionality.

Upon looking at our given choices, we can see that equation represented by option B is in form of direct proportional equation, where k equals 3.

Therefore, the equation is direct proportional equation and option B is the correct choice.
