Find the midpoint of the line segment with the given endpoints

mezya [45]

Answer:

Option D.

Step-by-step explanation:

Hey there!

The given points are:(-4,-10) and (2,1).

Now; use midpoint formula,

$(x,y) = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Put all values.

$(x,y) = (\frac{ -4 + 2}{2} , \frac{ - 10 + 1}{2} )$

Simplify it.

$(x,y) = ( - 1, \frac{ - 9}{2} )$

$(x,y) = (- 1,- 4 \frac{1}{2}$ )

Therefore, your required answer is Option D.
