Hi..
$$3-6x$$≤ $$\frac{4x+2}{-2}$$....
3-6x≤ -2x-1
3+1≤6x-2x
1≤ x..
Only D fits in..

OR..

Find if equation fits in are x=0.... It doesn't.. B and E can be eliminated
Next try x =-1... Equation again doesn't fits.. A and C can be eliminated
Ans D

A
B
C
D
E

3-6x ≤ $$\frac{4x+2}{-2}$$

Multiply by -2, reverse inequality sign:

-2(3 - 6x) $$\geq$$ 4x + 2
-6 + 12x $$\geq$$ 4x + 2
8x $$\geq$$ 8
x $$\geq$$ 1

Only graph D satisfies.
