Question

Calculate mid point of $A(5,3)$ and $B(9,8)$

• A. $\frac{11}{2},7$
• B. $7,\frac{11}{2}$
• C. $7,11$
• D. $14,11$

Answer 1

The correct option is B $7,\frac{11}{2}$

The mid point of line segment joining $(x_1,y_1)$ and $(x_2,y_2)$ is $\left(\begin{array}{c}\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\end{array}\right)$
Mid point of AB $\Rightarrow \left(\begin{array}{c}\frac{5+9}{2},\frac{3+8}{2}\end{array}\right)$
$\Rightarrow \left(\begin{array}{c}7,\frac{11}{2}\end{array}\right)$
