kompoz [17]

Answer:

A) (4,1) C) (12,3) D) (20,5)

Step-by-step explanation:

Required

Which has a constant of proportionality of 1/4

To solve this, we make use of:

$y = kx$

Where k is the constant of proportionality.

Solve for x

$k = y/x$

Testing the given options

A) (4,1)

$k = y/x$

$k =1/4$

B) (8,12)

$k = y/x$

$k =12/8$

$k =3/2$

C) (12,3)

$k = y/x$

$k = 3/12$

$k = 1/4$

D) (20,5)

$k = y/x$

$k = 5/20$

$k = 1/4$

E) (12,6)

$k = y/x$

$k =6/12$

$k =1/2$
