Juan graphed the solution to the inequality StartAbsoluteValue r minus 4 EndAbsoluteValue greater-than 8 on the number line.

A number line going from negative 8 to positive 16. Open circles are at negative 4 and positive 12. Everything to the left of negative 4 and to the right of positive 12 is shaded.

Which inequality statement can be used to help determine if the graph is correct?
When r = negative 4, StartAbsoluteValue negative 4 minus 4 EndAbsoluteValue greater-than 8, which is true because 8 is equal to 8.
When r = negative 8, StartAbsoluteValue negative 8 minus 4 EndAbsoluteValue greater-than 8, which is true because –12 is less than 8.
When r = 14, StartAbsoluteValue 14 minus 4 EndAbsoluteValue greater-than 8, which is true because 10 is greater than 8.
When r = 8, StartAbsoluteValue 8 minus 4 EndAbsoluteValue greater-than 8, which is true because 4 is less than 8.
