Question

Do both tables show a proportional relationship between x and y

Answer 1

Considering the given tables in the quetion

the table below

from the table, notice that

when

x = 2, y = 4

when

x = 4, y = 8

when

x = 9, y = 18

From these values we can deduce that

for every value of x

`y=2x^{}`

This gives a proportional relationship between x and y

y = 2x
