A line with a parametric vector equation

Question

I am struggling with this question. Any help would be greatly appreciated

Answer 1

Do you know how a parametric equation works?

Hint

What does the value of (the parameter) $t$ have to be for the first coordinate to be $-8$?

Once you have this value of $t$, what is the value of the second coordinate?

Answer 2

If $x_1=-8$, then we have $t=-2$.

Can you take it from here ?
