Question

M(5, 7) is the midpoint of mc140-1.jpg. The coordinates of S are (6, 9). What are the coordinates of R? (4, 5) (7, 11) (5.5, 8) (10, 14)

Answer 1

the coordinate of R(4,5)

Answer 2

(4,5)

Explanation:

Given that M is the midpoint of the Line RS. Where the coordinates of M, R and S are

M(5,7)

R(X,Y)

S(6,9)

Here we have to find the valuer of X and Y

We will use the mid point formula which is given below.

`x=(x_1+x_2)/(2) \\y=(y_1+y_2)/(2)\\`

Let put the coordinated of M and S and find coordinates of R

`x=(x_1+x_2)/(2) \\5=(X+6)/(2) \\10=X+6\\X=4`

`y=(y_1+y_2)/(2)\\7=(Y+9)/(2) \\14=Y+9\\y=5`

Hence our coordinates are

(4,5)
