Answer:
D. <-7,-6>
Step-by-step explanation:
We have, the vectors u = <-6,3> and v = <1,9>
It is required to find the vector 'u-v'
So, we have, subtracting the given vectors,
u - v = <-6,3> - <1,9>
i.e. u - v = <-6-1,3-9>
i.e. u - v = <-7,-6>
Thus, the resultant vector 'u - v' is <-7,-6>.
Hence, option D is correct.
