Question

Question 1 Tell whether this table represent a proportional relationship. Give the constant proportionality.

O yes, k= 2/9
yes, k= 9
O not proportional

Answer 1

yes , k = 9

Explanation:

The equation of a proportional relationship is

y = kx ← k is the constant of proportion

To find k divide both sides by x

`(y)/(x)` = k

Check each ordered pair in the table

k =
`(18)/(2)` = 9

k =
`(45)/(5)` = 9

k =
`(63)/(7)` = 9

Thus the relationship is proportional with k = 9
