Thank you so much for your help! My first question is on part a, wouldn't the 1 and the 3 be flip flopped? (under the impression that we are using the (y2-y1)/(x2-x1) equation), because I keep ending up with (x+2) Secondly, about the question at the end of part b, what is that even asking? And thirdly, on part c, what is the "normal line equation"? Thank you again for all your help!
