Question

How do you know whether two quantities x and y are proportional? Every ratio yx for related pairs of x and y is equivalent. Every sum x + y is the same for related pairs of x and y. Every x term is a multiple of the previous term. Every difference x – y is the same for related pairs of x and

Answer 1

Answer:

Two quantities x and y are said to be proportional if ratio yx for related pairs of x and y is equivalent.

Step-by-step explanation:

Two quantities x and y are said to be proportional if ratio $yx$ for related pairs of $x$ and y is equivalent.

The symbol ∝ is used to denote the proportionality. For example, if $x$ is proportional to y, then it is represented as $x$∝y and if $x$ is inversely proportional to y, then it is represented as $x$ ∝ 1/y
