Answer 1

N64, you should post one question at a time. Don't you think 6 questions at once is asking a bit too much of the community here?

Answer 2

1. Use y2 - y1/ x2-x1 for the slope.
2. Use ((x1 + x2)/2, y1+y2/2))
4. In a circle equation, (x-h)^2 +(y-k)^2 =r^2
6. To find a perpendicular line to another, you tape the reciprocal of the original slope.

Answer 3

@Abs.Zero, I very much like the format of your answer. Good job.
