Question

Please help!!!! the other boxes under 4 and 15/2 are 10 and 5

Answer 1

see explanation

Explanation:

given that x and y are proportional relationships , then

y = kx ← k is the constant of proportionality

divide both sides by x

`(y)/(x)` = k

using corresponding values of x and y from each table to find k

first table

k =
`(10)/(1)` = 10

second table

k =
`(20)/(4)` = 5

third table

k =
`(15)/(2)`

fourth table

k =
`(4)/(1)` = 4
