Final answer:
The distance between the points (-23, 21.8) and (-7, 21.8) is 16 units, as they lie on the same horizontal line and we take the absolute value of the difference of their x-coordinates.
Step-by-step explanation:
The question asks about the distance between two points with the coordinates (-23, 21.8) and (-7, 21.8). To find the distance between these two points, which lie on a horizontal line (since their y-coordinates are the same), we simply subtract the x-coordinates.
The formula for distance in a one-dimensional case along a line is the absolute value of the difference between the two points.
- First, find the difference between the x-coordinates: -7 - (-23) = -7 + 23 = 16.
- Then, take the absolute value of the difference: |16| = 16.
Therefore, the distance between the two points is 16 units.
