Question

Will mark brainliest Which table of ordered pairs represents a proportional relationship?

Answer 1

Answer:

2y = x, which is a proportional relationship.

Step-by-step explanation:

See the table attached.

The table gives the ordered pair represents a proportional relationship.

Take at least two pairs of the value of x and y.

Let they are (6,3) and (10,5).

Now, the equation for the straight line passing through the two points is given by  

$\frac{y - 5}{5 - 3} = \frac{x - 10}{10 - 6}$

⇒ 2(y - 5) = x - 10

⇒ 2y - 10 = x - 10

⇒ 2y = x

Hence, we can write x ∝ y and the constant of proportionality is 2. (Answer)
