Okay, so I am doing this tutorial for Econ but for some reason I cannot figure out the correct answer for slope. How know that to calculate slope it is rise over run but when I used that, I dont get the correct answer. Here is the problem:
and then here is the answer choices for the first question:
So, does anyone have any idea on how to solve this? If I followed rise over run the slope for A - B would be 1 right..? So why isn't an answer choice 1? I am so confused.. lol.
