I'm not sure what the question is but I have a possible explaination.
Step-by-step explanation:
I think it might be which shape each cross section being taken makes. The one on the top makes an oval, the second one makes a circle, and the one on the bottom makes a rectangle. I hope this answers your question. If not, sorry!
Work: I used the slope formula method which is y2 - y1/ x2 - x1. After plugging it in, the new equation is 4 - (-2) / 10 - 6. After subtraction, I had gotten 6/4. And when you divide 6/4, you get 1.5
