Which equation has a constant of proportionality equal to 0.25 ? Choose 1 answer: (A) y=25 x (B) y=(5)/(2)x (C) y=(1)/(4)x (D) y=(1)/(25)x

Define constant of proportionality: The constant of proportionality is the constant factor by which the input (x) is multiplied to get the output (y) in a directly proportional relationship, which can be represented as y = kx, where k is the constant of proportionality. We need to find which equation has k = 0.25.Check option (A): Let's check option (A) y = 25x. Here, the constant of proportionality would be 25, which is not equal to 0.25.Check option (B): Now, let's check option (B) y = (5/2)x. The constant of proportionality here is 5/2, which simplifies to 2.5, not 0.25.Check option (C): Next, let's check option (C) y = (1/4)x. The constant of proportionality here is 1/4, which is equal to 0.25.Check option (D): Finally, let's check option (D) y = (1/25)x. The constant of proportionality here is 1/25, which simplifies to 0.04, not 0.25.
