Unit 1: Geometry Basics Homework 3: Distance & Midpoint formulas
S(-4, -6) and T(-7, -3); Find R

The midpoint is ( -5.5, -4.5)

Step-by-step explanation:

Assuming R is the midpoint

To find the x coordinate of the midpoint, sum the x coordinates of the endpoints and divide by 2

( -4+-7)/2 = -11/2 = -5.5

To find the y coordinate of the midpoint, sum the y coordinates of the endpoints and divide by 2

( -6+-3)/2 = -9/2 = -4.5

The midpoint is ( -5.5, -4.5)
