Which of the coordinate points below will fall on a line where the constant of proportionality is 23? Select all that apply. A) (6,8)
B) (3,2)
C) (6,4)
D) (9,6)
E) (12,8)

(3,2)

(6,4)

(9,6)

(12,8)

Step-by-step explanation:

Constant of proportionality is 2/3

This means that:

Thus, y should be less than x, which removes option A.

B) (3,2)

x = 3, so:

So (3,2) is on the line

C) (6,4)

x = 6, so:

So (6,4) is on the line

D) (9,6)

x = 9, so:

So (9,6) is on the line

E) (12,8)

x = 12, so:

So (12,8) is on the line

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
