See the attached for the polynomial long division.
I just want to reccomend desmos, it really helped me with graphing because im not so good at it
But what I got is:
x-4y=-18
x=-18+4y
Root(-18,0)
Y-intercept: (0, 9/2)
The answer is the first option, <-20, -42>.
We can find this by first finding what -2u would equal by multiplying <5, 6> by -2. This gives us <-10, -12>.
Then we need to find out what 5v is equal to, by multiplying <-2, -6> by 5 to get <-10, -30>.
Now that we know what -2u and 5v are, we can substitute them into the equation and get
<-10, -12> + <-10, -30>, which we can split up into -10 - 10 = -20, and -12 - 30 = -42, so your final answer is <-20, -42>.
I hope this helps!
