10, subtract 2 from 12 and the answer is 10
<span>17x − 8x + 2 = 9x + 2 ...............combine like terms
answer
</span><span>2 + 9x, because (17x − 8x) + 2 = 9x + 2 = 2 + 9x ............commutative property</span><span>

I'm pretty sure it's d. y=-3x
The line of best fit helps you make predictions based upon ordered pairs that you have plotted. The independent variable is on the x axis. The dependent variable is on the y axis. You find the slope by plugging in the order pairs into a calculator which gives you the line of best fit.
Hope this helped :)
I could be wrong however, I'm sure it's: -3x-5= 15v (two negatives become a positive. -3-u becomes 3u. (Two negatives also become a positive), and -3+6 is -3x6= -18. Hence, the answer is: 15v+3u-18.
