Which equation represents a proportional relationship? a. y=15x b. y=−x c. y=−5(x+1) d. y = 5x + 1

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 or

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

case A)

Is a linear equation that passes through the origin

therefore

The case A) represent a proportional relationship

case B)

Is a linear equation that passes through the origin

therefore

The case B) represent a proportional relationship

case C)

Is a linear equation but not passes through the origin

therefore

The case C) does not represent a proportional relationship

case D)

Is a linear equation but not passes through the origin

therefore

The case D) does not represent a proportional relationship
