Which of the following does not form a proportion? 5/8 = 10/16
25/40 = 10/16
15/24 = 10/16 5/9 = 10/16

5/9 = 10/16 is not proportional

Step-by-step explanation:

5/8=10/16 (If you simplify you will get 5/8=5/8 which is true)

25/40=10/16 (If you simplify you will get 5/8=5/8 which is true)

15/24=10/16 (If you simplify you will get 5/8=5/8 which is true)

5/9≠10/16 (If you simplify you will get 5/9=5/8 which is not true)

Hope this helps

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
