If the ratio y/x is the same for all related pairs of x and y, what does that mean

Verizon [17]

Answer:

The same ratio indicates that there is a proportional relationship between y and x.

Step-by-step explanation:

We know when y varies directly with x, the equation is

y ∝ x

$y=kx$

$k\:=\:\frac{y}{x}$

Here,

k is the constant of proportionality.

The ratio y/x indicates that k is a constant of proportionality.

Thus, the same ratio indicates that there is a proportional relationship between y and x.

When x increases, y increases, and when y decreases, x also decreases.
