Answer:
it is the last option
Explanation:
i say this because in order to find a proportional relationship, you need to see if the values match. i will show you how to do this (it is quite simple). so do you see the 1 in the x-value and the 1 in the y-value and the 2 in the x-value and the 0.5 in the y-value? well its like multiplying pretty much. you do 1×1 and that equals 1. than 2×0.5 equals 1 as well. so that problem is proportional. it will work with the other numbers beside it as well. 7 and 4 which equal 28 and 8 and 3.5 which equal 28. its proportional! have a great day!
