Answer:
D. v=<20, 52>
Step-by-step explanation:
Vector u can be written in component form by subtracting its initial point from its terminal point:
u = (5, -4) -(15, 22) = <-10, -26>
We are told that v = -2u, so ...
v = -2<-10, -26> = <20, 52>
_____
Multiplying a vector by -1 reverses its direction; multiplying it by some factor k changes its magnitude by a factor of k. To reverse the direction and double the magnitude, we can multiply u by -2.
All of the rays indicated coincide. The points lie on the same line or ray. For explanation, please refer to the attachment.
