Find the midpoint of the line segment with the given endpoints: (-1, -6) and (-6, 5).

Vikentia [17]

Answer:

Step-by-step explanation:

First, we will find the midpoint for the x - coordinate first.

Midpoint (x) = $\frac{-1+(-6)}{2} \\=\frac{-1-6}{2} \\=\frac{-7}{2} \\=-3.5$

Now we will find the midpoint for the y - coordinate.

Midpoint (y) = $\frac{-6+5}{2} \\=\frac{-1}{2} \\=-0.5$

Therefore from these 2 values we know that the midpoint of this 2 points is (-3.5,-0.5)
