Using line segments, it is found that:
----------------------------
[tex]Q - P = \frac{2}{5}(R - P)[/tex]
This is used to find the x and y coordinates of Q.
----------------------------
Thus:
[tex]Q - P = \frac{2}{5}(R - P)[/tex]
[tex]x - 1 = \frac{2}{5}(11 - 1)[/tex]
[tex]x - 1 = \frac{2}{5}10[/tex]
[tex]x - 1 = 4[/tex]
[tex]x = 5[/tex]
----------------------------
Thus:
[tex]Q - P = \frac{2}{5}(R - P)[/tex]
[tex]y - 3 = \frac{2}{5}(15 - 3)[/tex]
[tex]y - 3 = \frac{24}{5}[/tex]
[tex]y - 3 = 4.8[/tex]
[tex]y = 7.8[/tex]
The coordinates of Q are (5,7.8).
----------------------------
[tex]M = (\frac{1 + 11}{2}, \frac{3 + 15}{2}) = (\frac{12}{2}, \frac{18}{2}) = (6,9)[/tex]
The midpoint of segment PQ is M(6,9).
