the distance between (-3,5) and (-12,5)
since y coordinates same the distance between is the distance between -3 and -12 which is 9 units

or, find it using distance formula:
Solved by pluggable solver: Distance Between 2 points
The distance formula is sqrt%28%28%28x%5B2%5D-x%5B1%5D%29%5E2%29%2B%28%28y%5B2%5D-y%5B1%5D%29%5E2%29%29. Plug in the numbers,
sqrt%28%28%28-12-%28-3%29%29%5E2%29%2B%28%285-%285%29%29%5E2%29%29
sqrt%28-9%5E2%2B0%5E2%29 The distance is 9.

.

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.

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!!
