Find the horizontal distance between points C(3.5, −0.25) and D(0.5, −0.25).

3 units

Step-by-step explanation:

Since the y-coordinate is the same. Therefore, there is a straight horizontal line between the two points. So, again, since the y-coordinates are the same, we can subtract C(x) (the x-coordinate for point C) from D(x) (the x-coordinate for point C)

C(x) = 3.5

D(x) = 0.5

3.5 - 0.5 = 3

Therefore, the distance between the two points is 3 units
