Question

The quantities of x and y are proportional. Find the constant of proportionality (r) in the equation y=rx.
R=?

Answer 1

Step-by-step explanation:

If the ratio (yx) of two variables (x and y) is equal to a constant (k = yx), then the variable in the numerator of the ratio (y) can be product of the other variable and the constant (y = k ⋅ x). In this case y is said to be directly proportional to x with proportionality constant k.
