It would really help a lot if I could see the sketch that's printed
next to that question in the place you copied it from. In fact,
there's no possible way to answer if I can't see the choices.
(Also, I suspect that you didn't do too good of a copying job.)

It is -1.2... (repeating).
6.5 is halfway.
A line segment is a straight line that has endpoints.

6.5 is halfway.
A continuous line goes on forever, the mathematic symbol for infinity is a sideways number 8 because U'r able to draw that symbol infinitely over & over again. A normal line starts with a point A & finishes with the point B, but a line that is continuous has no point B.

(-4, 6)
If the point is x=a, y=b ie the point (a,b) , then your line is y-b=m(x-a) where m is the gradient (anything you like).
10 Nodes A B C D E A-B B-C C-D D-E A-C A-D E-B E-C E-A B-D
From that list, I'll have to go with 'B'.
(B - A)2 - 81 or (B - A + 9)(B - A - 9) If the starting point, A, is taken as zero the the expression simplifies to (B + 9)(B - 9)
