Great job, very fluent teaching. But one thing though, I couldn't quite wrap my head around the addition/subtraction property being used with point slope formulas at . The part I didn't understand is how x1 and y1 counted as a constant number and were able to be used throughout the formula. I am not doubting the formula at all, I just can't quite understand this that's all.

But wait how do you know that in the end you need to subtract or add like you said -4 and +5, so how do you know do you need to subtract or add? If anyone knows, please tell me I really need help. My exam is tomorrow.😢😅

Hey, it was a wonderful explanation until you got it wrong... The problem is everybody's watching your video to get the answers right.
