Question

Sample Response: His work is not correct. You first must switch x and y and then solve for y.

Compare your response to the sample response above. What did your explanation include?

the conclusion that the work was incorrect

an explanation that Talib did not switch the variables at the start

an explanation that Talib did not solve for the variable y

Answer 1

All three. The explanation said the work was incorrect, stated you must switch x and y (implying Talib didn’t), and said to then solve for y (implying he hadn’t solved for y).
