My understanding of the PPF is that the slope relative to the x-axis represents the opportunity cost (of the good on the x-axis), while the opportunity cost of the good on the y-axis is 1/slope.

For this question, as more albums are produced, we are moving from left to right along the x-axis, where the slope is decreasing in absolute magnitude. This would imply that the opportunity cost of the y-axis good is increasing. However, the answer key states the exact opposite.

i ask gemini, chatgbt and deepseek they all say the answer khan academy gave me is wrong. But I'm a only a beginner I just can't trust myself
Appreciate any advice thanks.

So I'm a second year BIO student taking a Critical Reading and Writing course as an elective. We are currently working on literary analysis essays for the book "Ducks: Two Years in The Oil Sands" and my prompt is:

"Explore what Ducks: Two Years in the Oil Sands suggests about the relationship between industrial development and the environment. Develop an interpretation of what the memoir reveals about the environmental consequences of resource extraction and the relationship between economic activity and environmental responsibility, and analyze how Beaton develops this idea through specific experiences, events, and details in the memoir."

Now I understand this probably isn't of much help since I doubt you've read the book, much less done thorough literary analysis of it, but I just really need some help here. My class is asynchronous, meaning there is NO class, just notes posted for us to read and discussions to do. But the notes aren't very thorough and do not adequately replace entire lectures whatsoever.

Now, my problem: everything I write apparently contains zero literary analysis of the book. I don't disbelieve my professor, but I'm starting to think I just don't grasp what literary analysis actually means. I've read the book twice now so it's not like I'm just making up the stuff I write. He refuses to tell me over email what exactly literary analysis is, just that my work contains none of it. What the notes contain is not enough for me to understand what literary analysis is and why my work isn't that.

I can supply the work I did which my professor said contained zero literary analysis if you ask, I'm just a bit nervous to since apparently it's so bad. It's just a draft paragraph, a secondary source, and thesis statement.

I had a surgery and missed a week of high school and need an explanation as to what the hell im looking at.
