Yes it does in fact help, thank you very much. I was able to figure it easily but it's all far back in my head.. but I kinda remember the rules with the exponents. I always found the roots to be difficult but I think it will be understandable this time.
At this point, I need to re-learn how to do, for instance, this: (-8,8) & (-3,-5) to y = ax + b
I know it's a slope and it touches the coordinates.
and as I'm writting I'm think, it probably has something to do with "y2-ya1/x2-x1" ?
