What is the constant of proportionality in this proportional relationship?
a) 4/5
b) 5/4
c) 4
d) 5

Answer 1

a

Explanation:

The equation of a proportional relationship is

y = kx ← k is the constant of proportionality

Divide both sides by x

`(y)/(x)` = k

To find k use any ordered pair from the table

Using (2,
`(5)/(2)` ) , then

k =
`(2)/((5)/(2) )` = 2 ×
`(2)/(5)` =
`(4)/(5)`
