Answer:
c-12>-16
+12
C > - 4
So, c is greater than - 4.
Draw a number line. (Pick starting point of your choice. I. E. - 6 to 4)
Draw a circle at - 4.
Draw a horizontal line from the circle at - 4 to 2, for example.
Draw an arrow head on the line.
(BTW the arrow head & horizontal line can exceed 2 if you want it to; as long as your showing clearly C can be any number greater than - 4, with arrow pointing to the right as shown below)

o---------------------> -4 - 3 - 2 - 1 0 1 2
Hope this helps!
