Mid-point of the line-segment joining the points (– 5, 4) and (9,

Answer: Option B : B Midpoint of theline segment joining ( x 1 , y 1 ) and ( x 2 , y 2 ) is given by ( x 1 + x 2 2 , y 1 + y 2 2 ) ∴ Mid-point of the line-segment joining the points (– 5, 4) and (9, – 8) = ( − 5 + 9 2 , 4 − 8 2 ) = (2,-2)

Question

Mid-point of the line-segment joining the points (– 5, 4) and (9, – 8) is:

Options:

A . (– 7, 6)

B . (2, – 2)

C . (7, – 6)

D . (– 2, 2)

Answer: Option B
:
B
Midpoint of theline segment joining

(x_{1}, y_{1})

and

(x_{2}, y_{2})

is given by

(\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})

∴

Mid-point of the line-segment joining the points (– 5, 4) and (9, – 8) =

(\frac{- 5 + 9}{2}, \frac{4 - 8}{2})

= (2,-2)
