The correct interpretation of the inequality -2 < 1 as a statement about the relative position of -2 and 1 on a number line is:
-2 is 3 units to the left of 1.
To detail the reasoning, -2 is a smaller number than 1, so it is indeed positioned to the left of 1 on the number line. The distance between -2 and 1 is 3 units (1 - (-2) = 3).
