.

Looking into coordinates, you should understand that the line is HORIZONTAL, parallel x-axis (since y = const = 5).



Hence, the length of the segment between the endpoints is

the difference of x-coordinates  -3 - (-12) = -3 + 12 = 9 units.    ANSWER

Solved.

What is the distance between (-3,5) and (-12,5)?
Same y-coordinate indicates a 0 (zero) slope. 
Therefore, you just need to SUBTRACT the SMALLER x-coordinate from the LARGER x-coordinate, thereby getting:
That's ALL!!
