Question

Find the mid-point of AB where A and B are the points $(-5,11)$ and $(7,3)$.

• A. $(1,7)$
• B. $(0,0)$
• C. $(1,0)$
• D. $(0,7)$

Answer 1

The correct option is A $(1,7)$

Midpoint of two points ${(x}_1,y_1)$ and ${(x}_2,y_2)$ is calculated by the formula $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Using this formula, mid point of AB $=(\frac{-5+7}{2},\frac{11+3}{2})$

$=(1,7)$
