Which linear equation represents a proportional relationship?

A)y = x + 2B)y = 3x + 0.2C)y = −0.3xD)y = −3x +

Correct option:

C) y = −0.3x

A proportional relationship between two variables occurs when their ratios are equivalent. In other words, we can write one variable as the product of a constan value and the other variable, so:

So this is the equation of a line that passes through the origin. By comparing this equation with our options, we see that the only option that meets this requirement is option c)
