Question

Which number line represents the solutions to |x – 2| = 6?

Answer 1

Answer: D IS THE ANSWER

Answer 2

Since this is an absolute value expression you have to solve for both the positive and negative case.

x-2=6 add two to both sides

x=8

and

x-2=-6 add two to both sides

x=-4

So x=-4 and 8

So the solution on the number line is solid dots as x=-4 and x=8
