Question

Why can you use the constant of proportionality with any representation?

Answer 1

Answer:

1. The number k is called the constant of proportionality. One important way of thinking about this constant k is that it tells us how much y increases by if we increase x by exactly 1. to express that y is directly proportional to x.

Answer 2

Proportionality constant can be used with any representation to determine how a variable is changing with respect to others.

Variation is a method comparing the nature of a variable with another variable using a constant called the proportionality constant

For instance, if a variable y is directly proportional to x, it is expressed as;

y ∝ x

y = kx

k is the proportionality constant relating y to x and shows that as the value of y is increasing, the value of x is also increasing and vice versa.
