Question

In what form is an equation that relates two proportional quantities x and y?

Oy=k+x, where k is the constant of proportionality
O y = kx, where k is the constant of proportionality
k
where k is the constant of proportionality
O y
y=
k
where y is the constant of proportionality

Answer 1

B.
`y = kx` , where k is the constant of proportionality.

Explanation:

Given that quantity x and y is directly proportional to each other, which means as one variable increases, the other increases as well. Thus, the constant of proportionality, which is often denotes with the alphabet k, can be represented by the following equation:

`y = kx` , where, k is the constant of proportionality.

Constant of proportionality, k, is gotten when you divide the value of y by the value of x.
