24kx = 6
kx = 6/24
kx = 1/4
x = 1/4/k
x = 1/4k
Answer: A) X = 1/4k or the first option.
Add the 2 values togetehr
The two inequalities can be rewritten as

The solution is composed by every point below the graph of the line
, and above the horizontal line 
To draw the line
we can build a little table (only 2 points are required):

So, if you draw the points (0,2) and (1, -2) and connect them, you'll have your line.
To draw the line
, simply pick any point with y coordinate -2, for example (0, -2), and draw a horizontal line.
Choose the above/below areas as specified above to solve the system.
