Question

Which of the following is the midpoint of a line segment with endpoints -4 and 7?

A. 1.5
B. 0
C. -3
D. 5.5

Answer 1

A.1.5 is the correct answer.

Answer 2

A. 1.5

Explanation:

End points of the line segment:

• - 4 and 7

Length of line segment:

• 7 - (-4) = 11

Half length of the line segment:

• 11/2 = 5.5

Midpoint is at same distance from either end:

• 7 - 5.5 = -4 + 5.5 = 1.5

Midpoint is 1.5
