If R is the midpoint of segment AM, find midpoint R

Coordinate A is (-2,4)
Coordinate M is (-2,1)

1 answer

To find the midpoint \( R \) of the segment \( AM \), you can use the midpoint formula:

\[ R = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \]

where \( (x_1, y_1) \) are the coordinates of point \( A \) and \( (x_2, y_2) \) are the coordinates of point \( M \).

Given:

  • Coordinate \( A = (-2, 4) \)
  • Coordinate \( M = (-2, 1) \)

Now, substitute the coordinates into the midpoint formula:

  1. Calculate the x-coordinate of \( R \): \[ x_R = \frac{-2 + (-2)}{2} = \frac{-4}{2} = -2 \]

  2. Calculate the y-coordinate of \( R \): \[ y_R = \frac{4 + 1}{2} = \frac{5}{2} = 2.5 \]

Thus, the coordinates of midpoint \( R \) are:

\[ R = (-2, 2.5) \]
