Answer:

(c) see attached

Explanation:

You want the number line that shows the solutions to |-2x| = 4.

Solution

The absolute value equation resolves to two equations:

  • -2x = 4 ⇒ x =-2
  • -2x = -4 ⇒ x = 2

The solution will be plotted on the number line as solid dots at -2 and 2, as shown in the attachment.
