To calculate the midpoint, we just need to calculate the mean for each coordinate.
Given the set of points
[tex]\lbrace(x_1,y_1),(x_2,y_2)_{}\rbrace[/tex]
The coordinate of the midpoint is given by
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Now, let's calculate the midpoint for our set of points
[tex]\lbrace(-4,-3),(7,-5)\rbrace[/tex]
The midpoint is:
[tex](\frac{-4+7}{2},\frac{-3-5}{2})=(1.5,-4)[/tex]
