It is clear you understand the math behind the questions. You use desmos and an algebraic way to solve the problem, so the learner has a variety of ways to solve future questions. Good job on that! However, when you were teaching, you mostly asked them if they understood your process directly, not if they could extend that understanding to higher-level concepts. In the future, you could try to engage with your learner more, but I understand that in live help sessions, it is difficult to do that :)
