PB is a line segment on a number line. It has endpoints at -2 and 12. What is the coordinate of its midpoint?

midpoint is the average of the endpoints

Okay thanks

To find the coordinate of the midpoint of a line segment, you can use the formula:

Midpoint = (Endpoint A + Endpoint B) / 2

In this case, the endpoints of the line segment PB are -2 and 12. So, plugging these values into the formula, we get:

Midpoint = (-2 + 12) / 2
Midpoint = 10 / 2
Midpoint = 5

Therefore, the coordinate of the midpoint of the line segment PB is 5.
