What is the midpoint between point A and B if point A is at (7, -4) and point B is at (-9, 5)

1 answer

To find the midpoint between two points \( A(x_1, y_1) \) and \( B(x_2, y_2) \), you can use the midpoint formula:

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

Given point \( A(7, -4) \) and point \( B(-9, 5) \):

  • \( x_1 = 7 \)
  • \( y_1 = -4 \)
  • \( x_2 = -9 \)
  • \( y_2 = 5 \)

Now, plug the values into the formula:

\[ \text{Midpoint} = \left( \frac{7 + (-9)}{2}, \frac{-4 + 5}{2} \right) \] \[ = \left( \frac{7 - 9}{2}, \frac{1}{2} \right) \] \[ = \left( \frac{-2}{2}, \frac{1}{2} \right) \] \[ = (-1, 0.5) \]

Therefore, the midpoint between point A and point B is \( \boxed{(-1, 0.5)} \).
