The horizontal distance between (16, -24) and (-3, -24) is 19 units.
Step-by-step explanation:
We can calculate the horizontal distance by finding the difference between the x-coordinates of the two points.
Horizontal distance = difference in x-coordinates = (-3) - 16 = -19
However, the distance is negative, which doesn't make sense as distance is always positive. So we take the absolute value of the difference to get the actual distance.
|Horizontal distance| = |-19| = 19
Therefore, the horizontal distance between the two points is 19 units.
