Translation:
The length of the segment AB is equal to 5 units. If the point A(-2) is the left end point of the segment, then find the coordinate of the right end point B.
Solution:
Let A and B be points on the number line, and let their coordinates be \(x_A\) and \(x_B\) respectively. We are given that \(x_A = -2\). We are also given that the length of the segment AB is 5. Since B is to the right of A, the length of the segment is equal to \(x_B - x_A\).
Thus, we have:
$$x_B - x_A = 5$$
$$x_B - (-2) = 5$$
$$x_B + 2 = 5$$
$$x_B = 5 - 2$$
$$x_B = 3$$
Therefore, the coordinate of point B is 3.
