Answer:
D
Step-by-step explanation:
its D.
My reasoning is that the question is asking for quantities that are proportional. That word in specific is used. So, ratios are proportional.
Now, this chart is absoluetly not proportional in that sense. not only are the x and y's not going up at a constant rate, but the (x,y)'s are also so off!
2/5=.4
3/6=.5
6/15=.4
10/20= .5
If I remember this type of math correctly, the fact that there is a pattern of .4, .5 does not matter AT ALL.
This chart is still very unproportional, and the correct reasoning is D.
The y-values not increasing at a constant rate is not the issue at all, so it isnt b , if you are wondering why D is correct and B isn't.
Here, take this example:
5,10
20,40
200,400
These y values are NOT increasing at any type of constant rate. However, the ratio is the same. That is all that matters.
Final answer: D.
I hope I was able to help!
