Answer:
C.Subtract x- vlaues 8-3=5 units
Explanation:
We are given that two points (3,4) and (8,4)
We have to find that which shows how to find the horizontal distance between (3,4) and (8,4).

We have to find the horizontal distance
Horizontal distance is the difference of two x-values.
Therefore, horizontal distance=8-3=5 units
Hence, Option C is true.
