M35is the midpoint between Rxyand S100 Find the coordinates

M(3,5)is the midpoint between R(x,y)and S(10,0).

Find the coordinates of R.

Solution

We have to use the mid point formula where midpoint (x,y) is given by

x=(x₁+x₂)/2 and y=(y₁+y₂)/2

So we get

3=(x+10)/2 , -5=(y+0)/2

x+10=6 , -10=y

x=-4, y=-10

Point R (-4,-10)
