y = (answer)x

Answer 1

y = 5x

Explanation:

It can be observed that as ‘x’ increases, ‘y’ also increases.

It can also be observed that

`(y)/(x)` = the same constant for all four sets of values

k =
`(10)/(2) = (20)/(4) = (30)/(6) =(40)/(8)`=5

It can concluded that y is directly proportional to x:

y = kx Where k = constant of proportionality

For these four sets of values:

y = 5x
