MYP Mathematics, midpoint formula

How can we find the coordinates of the midpoint of line segment BC where B(10,50) and C(20,30) ?

Thanks

MYP Mathematics, midpoint formula

The coordinates of the midpoint of a line segment defined by the points $A(x_{1}, y_{1})$ and $B(x_{2}, y_{2})$ is given by the following formula:

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

Applying the above formula in our case we have

$(x_{m}, y_{m} )=( \frac{10+20}{2},\frac{50+30}{2} )=$

$=( \frac{30}{2},\frac{80}{2} )$

$=( 15, 40)$

Hope these help!
