A line is parameterized by $x= 8+8t$ and $y = 8+2t$.

(a) Which of the following points are on the section of the line obtained by restricting $t$ to nonnegative numbers (for each, enter Y if the point is on the section, and N if not)?
$\left(-24,0\right)$ :
$\left(24,12\right)$ :
$\left(48,18\right)$ :
Then, give one more point that is on the section of the line obtained by this restriction:

(b) What are the endpoints of the line segment obtained by restricting $t$ to $-2\le t\le 0$?
left endpoint :
right endpoint :

(c) How should $t$ be restricted to give the part of the line above the $x$-axis (give your answer as an interval for $t$, for example, (3,8) or [-2,Inf))?
$t$ must be in :
