a line segment on a number line has its endpoints at -9 and 6. Find the coordinate of the midpoint of the segment.

.(-9 +6) / 2 = -3/2 = -1.5.

can anyone help me?

See Similar Questions below.

the midpoint is the average of the two endpoints

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

Midpoint = (End Point 1 + End Point 2) / 2

In this case, the endpoints of the line segment are -9 and 6. Plugging these values into the formula, we get:

Midpoint = (-9 + 6) / 2

Simplifying this expression, we have:

Midpoint = -3 / 2

Therefore, the coordinate of the midpoint of the segment is -3/2.
