You need to find the value of y..
40=8y
40÷8=y
5=y
The value of y is 5
To find this, you have to find your slope with the given x and y values first. Use the equation Y2-Y1/X2-X1 for finding the slope.
4-1/3- -6
3/9= 1/3
Now you know your slope is 1/3, and you can basically assume your third answer listed is correct since none of the other ones contain a positive 1/3 but I will explain how to continue for future use. Next you can use one set of x and y values to plug into the equation y=mx+b, and plug in 1/3 for m as well.
4=1/3(3) + b
4 = 1 + b
-1 -1
3 = b
Now you have your y intercept and your slope, so you can make your equation.
Y= 1/3x + 3
A sixth is less than one half.
1/6 = 0.16
1/2 = 0.5

Answer:
![X = \left[\begin{array}{cccc}12&-24&8&16\end{array}\right]](https://tex.z-dn.net/?f=X%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D12%26-24%268%2616%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
A matrix is given by
![A = \left[\begin{array}{cccc}6&-12&4&8\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D6%26-12%264%268%5Cend%7Barray%7D%5Cright%5D)
Now, we have to find the matrix X if 
⇒ X = 2A
Now, multiplication of a constant with a matrix means multiplication with that constant with all the terms of the matrix.
So, ![X = \left[\begin{array}{cccc}6 \times 2&-12 \times 2&4 \times 2&8 \times 2\end{array}\right]](https://tex.z-dn.net/?f=X%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D6%20%5Ctimes%202%26-12%20%5Ctimes%202%264%20%5Ctimes%202%268%20%5Ctimes%202%5Cend%7Barray%7D%5Cright%5D)
