What is the correct formula to find the x-coordinate of the mid-point of a line segment between points A and B?
What is the correct formula to find the x-coordinate of the mid-point of a line segment between points A and B?
- $x = rac{2x_1 + 2x_2}{2}$
- $x = rac{x_1 + x_2}{2}$ (correct)
- $x = x_1 + x_2$
- $x = rac{x_1 - x_2}{2}$
