Answer:
its an equation between two variables that gives a straight line when plotted on a graph.
Step-by-s
I'll need a picture of your box plot to answer that question
The general form is ax²+bx+c=0,
so at least we know b has to be 0. None of the values match unless we multiply everything by 4. That leads to answer B, a=1, b=0 and c=20
I don't think that's possible.
