Math Problem Statement

In the Cartesian plane, segment AM is a median of triangle ABC. Given points A(-9, 6), B(7, -5), and C(-13, -2), what are the coordinates of point M?

Solution

The problem is asking to find the coordinates of point MM, given that segment AMAM is a median of triangle ABCABC.

Key Information:

  • A(9,6)A(-9, 6)
  • B(7,5)B(7, -5)
  • C(13,2)C(-13, -2)
  • AMAM is a median, so MM is the midpoint of side BCBC.

Step-by-step solution:

  1. Find the coordinates of MM, the midpoint of segment BCBC: The midpoint formula is: M(x1+x22,y1+y22)M\left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right) where (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) are the coordinates of points BB and CC.

    Plugging in the coordinates of B(7,5)B(7, -5) and C(13,2)C(-13, -2): Mx=7+(13)2=62=3M_x = \frac{7 + (-13)}{2} = \frac{-6}{2} = -3 My=5+(2)2=72=3.5M_y = \frac{-5 + (-2)}{2} = \frac{-7}{2} = -3.5

Thus, the coordinates of point MM are (3,3.5)(-3, -3.5).

Final Answer:

The coordinates of point MM are (3,3.5)(-3, -3.5).
