which of the following are proportions?

25/10= 5/2

3/4= 8/10

2/8= 3/12

3/4= 15/20

Yuh yeet honestly idk

Y=-3x is the correct answer

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
