Question

What is the constant of proportionality?

a) The constant factor that relates two directly proportional quantities.
b) A number that never changes in a proportionality relationship.
c) A variable that depends on the other variable in a proportion.
d) The result of dividing two inversely proportional quantities.

Answer 1

The constant of proportionality is the constant factor that relates two directly proportional quantities.

Step-by-step explanation:

The constant of proportionality is the constant factor that relates two directly proportional quantities. It is a number that never changes in a proportionality relationship. For example, in the equation y = kx, where y and x are directly proportional, k is the constant of proportionality. It represents the ratio between y and x and remains the same throughout the relationship.
