Answer:
Second from the top
The answer you have selected:
40:8 , 50:10, 60:14, 90:18
Proportions can be viewed as fractions:
40/8, 50/10, 60/14, 90/18
Now we have to simplify these fractions
5 , 5 , 4.3, 5
Unfortunately, they do not all come out to the same number, so this answer is incorrect
The second answer from the top:
4/2 , 7/3.5, 8/4, 10/5
These all equal 2 when simplified
2, 2, 2, 2
This shows a proportional relationship between x and y. If you would like to continue to make sure the bottom two are incorrect, you can use the steps that I have used for the first two. Hope this helps :)
