To find the coordinate of the midpoint, we can use the midpoint formula, which states that the coordinate of the midpoint of a line segment is the average of the coordinates of its endpoints.
In this case, the coordinates of the endpoints are -2 and 12. To find the average, we sum up the coordinates and divide by the number of endpoints:
(-2 + 12) / 2 = 10 / 2 = 5
Therefore, the coordinate of the midpoint of PB is 5.
PB is a line segment on a number line, it has endpoints at -2 and 12. What are the coordinates of its midpoint?
