Question

PLEASE HELP !!!! HELP!!label each equation is proportionality or non proportional Help

y=9/x

y=x-12

h=3d

f=1/3e
​

Answer 1

y=9/x => proportional

y = x - 12 ==> non-proportional

h = 3d ==> proportional

f = 1/3 e = proportional

Explanation:

A proportional equation is of the general form

y = kx (directly proportional) or

y = k/x (inversely proportional)

k is known as the constant of proportionality

y = 9/x ==> k = 9 proportional
y = x - 12 cannot be expressed as y = kx or y = k/x

h = 3d ==> k = 3 proportional

f = 1/3 e ==> k = 1/3 proportional
