Question

If the endpoints of ab are a(-2,3) and b(1,8) , which is the correct way to determine the coordinates of point c , the midpoint of line ab ?

Answer 1

------------------------------------------------------------------------------------
Formula
------------------------------------------------------------------------------------
$Midpoint = \bigg( \frac{X_1 + X_2}{2} , \frac{Y_1 + Y_2}{2} \bigg)$


------------------------------------------------------------------------------------
Find Midpoint of (-2,3) and (1,8)
------------------------------------------------------------------------------------

$Midpoint = \bigg( \frac{-2+ 1}{2} , \frac{3 + 8}{2} \bigg)$

$Midpoint = \bigg( -\frac{1}{2} , \frac{11}{2} \bigg)$


$\Longrightarrow \boxed {\bf \text {Answer: c = } \bigg( -\frac{1}{2} , \frac{11}{2} \bigg)}$
