4. m(7, 3) is the midpoint of rs. the coordinates of point s are (8,4). what are the
coordinates of r?
2vs
find sr

The co-ordinates of point R is (6 , 2)

Given that M(7, 3) is the midpoint of RS

Also co-ordinates of point S is (8, 4)

To find: co-ordinates of point R

The midpoint of two points and is given as:

Here midpoint M = (7, 3) and point S

Point R =

Substituting the values in formula we get,

Comparing both the sides we get,

and

On solving,

Also,

Thus the co-ordinates of point R is (6 , 2)

its 69.420
