The set of numbers indicated on the number line goes from -5 to 7, including -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, and 7. 
In set builder notation, this can be expressed as {x | -5 ≤ x ≤ 7}, where x is an element of the set. 
Out of the given choices, only choice C expresses this range of numbers. The set contains all numbers between (but not including) -5 and 15. In set builder notation, this can be expressed as {x | -5 < x < 15}. The only choice that matches this set is C, which has the correct digits in the middle coordinate (f69).
