Point R is the midpoint of line QS. R is located at (5, -7.5) S is located at (-1,-13) What is the location of Point Q?
Lisa [10]

Answer: ( 11, -2 )

Step-by-step explanation:

The mid point of a line is calculated using the formula:

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

From the question , the mid point is already given , substituting , we have :

(5 , - 7.5 ) = (\frac{x-1}{2} , \frac{y-13}{2} )

Equating the x component to x and the y component to y , we have

5 = \frac{x-1}{2}

x - 1 = 10

x = 11

Also

- 7.5 = \frac{y-13}{2}

-15 = y - 13

-15 + 13 = y

Therefore : y = -2

Therefore : the location of point P is ( 11, -2 )
