Find the distance between points C (-4.7) and D (-0.8) on the coordinate line.

The distance between two points is determined by the following general formula:

s = √ ((x2 – x1) ^ 2 + (y2 – y1) ^ 2), where x1, x2, y1, y2 are the coordinates of each of the two points. In our case, only one straight line is considered, which means that there are no coordinates y1 and y2. The formula takes the form s = √ ((x2 – x1) ^ 2, i.e. s = x2 – x1 = -0.8 – (-4.7) = -0.8 + 4.7 = 3.9.

Answer: s = 3.9.
