Question

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


A. y=k+x, where k is the constant of proportionality


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


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


D. y=xk, where y is the constant of proportionality

Answer 1

Step-by-step explanation:

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Answer 2

Answer:

hope it helps you ( not exactly)

Step-by-step explanation:

constant of proportionality (k = y/x) which is the constant ratio between two proportional quantities y/x denoted by the symbol k which may be a positive rational number. The x value is directly proportional to the y value such as in the equation y = kx.
