Question

The Constant of Proportionality from the following equation is:
y= 7/9x

Answer 1

`(7)/(9)`

Explanation:

A direct variation function is in this general form:

`y = kx\\\rule{150}{0.5}\\k -\text{ Constant of Proportionality}`

Since
`(7)/(9)` is in 'k's place, it is the Constant of Proportionality.

Hope this helps you.

Answer 2

k =
`(7)/(9)`

Explanation:

The equation of proportionality is

y = kx ← k is the constant of proportionality

y =
`(7)/(9)` x ← is in this form

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