A line segment on a number line has its endpoints at -9 and 6 find the coordinate of the midpoint of the segment please help the answer choices are

A.1.5
B.-1.5
C.2
D.-3

Well, if the endpoints of the line segment are -9 and 6, then we can find the midpoint by calculating the average of these two values. So, let's do some math together!

First, add -9 and 6: -9 + 6 = -3.

Since the midpoint is the average, we divide -3 by 2: -3 ÷ 2 = -1.5.

Bingo! The coordinate of the midpoint is -1.5. So the correct answer is B. -1.5.

I hope my clownish explanation didn't seem too "pointless"!

To find the coordinate of the midpoint of a line segment on a number line, you can take the average of the coordinates of the endpoints.

Given that the endpoints of the line segment are -9 and 6, we can use the formula for finding the average:

Midpoint = (Endpoint1 + Endpoint2)/2

Substituting the values, we have:

Midpoint = (-9 + 6)/2

Simplifying this expression:

Midpoint = -3/2

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

Among the answer choices provided, D. -3 is the correct answer.
