Do anyone know the answer?

C.

Step-by-step explanation:

To find which table is correct, you first have to plot the graph. First, pick some easy points on the X axis to graph. Some of these points could be -4, 0 and 4. Now you need to fill in the equation.

Y = -1/2*-4 - 2  = 0

Y = -1/2*0 - 2   = -2

Y = -1/2*4 - 2   = -4

Now you can plot the points and draw your line. Once you have done this, you check each table and see if all the points match up. Doing so would give you answer C.

Also the graph from the equation can be seen below

the solution is 12x-6y

entering that problem on the tube might get you an answer
