Question

Which of the following equations represents a proportional relationship.

y = 4x + 7
y = -2.5x - 3
y = 19x + 0
y = 27x - 4

Answer 1

The equation that represents a proportional relationship is y = -3x.

Step-by-step explanation:

In this question, we are looking for the equation that represents a proportional relationship. A proportional relationship is one in which two quantities vary in a consistent ratio. In the given options, the equation that represents a proportional relationship is y = -3x (option A), because the y-value is directly proportional to the x-value with a constant ratio of -3.
