alleryThe midpoint of the segment joining $(x_1,y_1)$ and $(x_2,y_2)$ is:
A$\left(\dfrac{x_1 x_2}{2},\ \dfrac{y_1 y_2}{2}\right)$
B$(x_1+x_2,\ y_1+y_2)$
C$\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$
D$\left(\dfrac{x_1-x_2}{2},\ \dfrac{y_1-y_2}{2}\right)$
Answer & Solution
Correct answer: C. $\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$
Midpoint = average of coordinates: ((x₁+x₂)/2, (y₁+y₂)/2).
