Question

HELP PLEASE!
I don't understand this at all, can somebody please help me understand these three questions? I really need to to do well on this..

Answer 1

I will help if at all possible :)

Answer 2

1. Line PB has endpoints at -2 and 12. What is the coordinate of its midpoint?

This is the first question and it makes absolutely no sense to me what so ever.

Answer 3

Would this be like a number line? And the number that would be in the middle of -2 and 12??

Answer 4

ok so if you have a number line you first point is going to be at -2, and you second point is going to be at 12 , they want you to find which point is smack in the middle of those so pint 4.5 is right in the middle sorry if this doesnt help XD- Bree
