C. y = 4x

Step-by-step explanation:

The equation of a proportional relationship:

y=ax\to\dfrac{y}{x}=a=const.

a - the constant of proportionality.

y=12x

y=3x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope of the line m, and the line passes trough the origin

so

case A) y=-3x+2  

Is a linear equation but does not passes trough the origin

case B) y=12x

Is a linear equation and passes trough the origin-----> represent a proportional relationship

case C) y=3x  

Is a linear equation and passes trough the origin-----> represent a proportional relationship

case D) y=2(x+13)

Is a linear equation but does not passes trough the origin

A. y = 3x/4

Step-by-step explanation:

 a proportional relationship between x and y is a straight line passing through the origin (0, 0).

The equation must be in the form y = kx.

y = 3x/4

y = 3/4x

a

Step-by-step explanation:

y=3x

thus, a proportional relationship equation is y=kx .Where k is constant

Answer from: alyssa337

As written here, both choices B and C represent proportional relationships:

... B. y = 12x

... C. y = 3x

One key to a proportional relationship is that when one variable is zero, so is the other. This will not be the case for selections A and D.

Answer from: naomirice24

B and D

Step-by-step explanation:

A proportional relationship has NO constant term.  Thus, we eliminate Answers A and C.

Answers B and D represent proportional relationships.
