Calculate midpoint M of segment AB.

Point A: (-1, 2)
Point B: (4, -2)

A. M is located at (3, 0)
B. M is located at (0.5, 1)
C. M is located at (1.5, 0)
D. M is located at (-2.5, 2)

To find the midpoint \( M \) of segment \( AB \), you can use the midpoint formula:

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

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

Given:

  • Point \( A: (-1, 2) \) \(\Rightarrow x_1 = -1\), \( y_1 = 2 \)
  • Point \( B: (4, -2) \) \(\Rightarrow x_2 = 4\), \( y_2 = -2 \)

Now, we can substitute these values into the formula:

\[ M = \left( \frac{-1 + 4}{2}, \frac{2 + (-2)}{2} \right) \]

Calculating the x-coordinate:

\[ \frac{-1 + 4}{2} = \frac{3}{2} = 1.5 \]

Calculating the y-coordinate:

\[ \frac{2 - 2}{2} = \frac{0}{2} = 0 \]

Thus, the midpoint \( M \) is:

\[ M = (1.5, 0) \]

Therefore, the correct answer is:

C. M is located at (1.5, 0).
