What is the midpoint of a line segment with the endpoints [tex][tex]$(-4,-3)$[/tex][/tex] and [tex][tex]$(7,-5)$[/tex][/tex]?

A. [tex][tex]$(1,-3.5)$[/tex][/tex]
B. [tex][tex]$(-4,1.5)$[/tex][/tex]
C. [tex][tex]$(-3.5,1)$[/tex][/tex]
D. [tex][tex]$(1.5,-4)$[/tex][/tex]



Answer :

To find the midpoint of a line segment with endpoints [tex]\((-4, -3)\)[/tex] and [tex]\( (7, -5) \)[/tex], we can use the midpoint formula. The midpoint formula is given by:

[tex]\[ \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \][/tex]

where [tex]\( (x_1, y_1) \)[/tex] and [tex]\( (x_2, y_2) \)[/tex] are the coordinates of the endpoints.

1. Identify the coordinates of the endpoints:
- [tex]\((x_1, y_1) = (-4, -3)\)[/tex]
- [tex]\((x_2, y_2) = (7, -5)\)[/tex]

2. Calculate the x-coordinate of the midpoint:
[tex]\[ \frac{x_1 + x_2}{2} = \frac{-4 + 7}{2} = \frac{3}{2} = 1.5 \][/tex]

3. Calculate the y-coordinate of the midpoint:
[tex]\[ \frac{y_1 + y_2}{2} = \frac{-3 + -5}{2} = \frac{-8}{2} = -4 \][/tex]

4. Combine the x and y coordinates to find the midpoint:
[tex]\[ \left( 1.5, -4 \right) \][/tex]

Thus, the midpoint of the line segment with endpoints [tex]\((-4, -3)\)[/tex] and [tex]\( (7, -5) \)[/tex] is [tex]\( \left(1.5, -4\right) \)[/tex].

The correct answer is:
D. [tex]\(\left(1.5, -4\right)\)[/tex]
