Points P, Q and R are collinear such that PQ : QR=2:3 point P is located at (1,3) and point R is located at (11,15)
balandron [24]

Using line segments, it is found that:

  • The coordinates of Q are (5,7.8).
  • The midpoint of segment PQ is M(6,9).

----------------------------

  • Point P is located at (1,3).
  • Point R is located at (11,15).
  • Point Q is located at (x,y).
  • PQ:QR = 2:3, which means that:

Q - P = \frac{2}{5}(R - P)

This is used to find the x and y coordinates of Q.

----------------------------

  • The <em>x-coordinate</em> of P is 1.
  • The <em>x-coordinate</em> of R is 11.
  • The <em>x-coordinate </em>of Q is x.

Thus:

Q - P = \frac{2}{5}(R - P)

x - 1 = \frac{2}{5}(11 - 1)

x - 1 = \frac{2}{5}10

x - 1 = 4

x = 5

----------------------------

  • The y<em>-coordinate</em> of P is 3.
  • The y<em>-coordinate</em> of R is 15.
  • The y<em>-coordinate </em>of Q is y.

Thus:

Q - P = \frac{2}{5}(R - P)

y - 3 = \frac{2}{5}(15 - 3)

y - 3 = \frac{24}{5}

y - 3 = 4.8

y = 7.8

The coordinates of Q are (5,7.8).

----------------------------

  • The midpoint of segment PQ is the mean of the coordinates, thus:

M = (\frac{1 + 11}{2}, \frac{3 + 15}{2}) = (\frac{12}{2}, \frac{18}{2}) = (6,9)

The midpoint of segment PQ is M(6,9).
