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( (X_1 + X_2)/(2) , (Y_1 + Y_2)/(2) \bigg)`


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


`Midpoint = \bigg( (-2+ 1)/(2) , (3 + 8)/(2) \bigg)`


`Midpoint = \bigg( -(1)/(2) , (11)/(2) \bigg)`



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