Question

find the coordinates of R if Q(-1,3) is the midpoint of PR and P has coordinates of (5,6)

Answer 1

Answer:

coordinates of R are (-7,0)

Step-by-step explanation:

It is given that a line segment is PR and Q is the mid point of the PR.

Coordinates of P are (5,6) and Q (-1,3) then we have to find the coordinates of R (x, y).

x coordinates of R will be -1 = $\frac{x+5}{2}$

                                         -2 = x + 5

                                          x = -2 - 5

                                          x = -7

y coordinates of R will be 3 =  $\frac{y+6}{2}$

                                          6 = y + 6

                                           y = 6 + 6

                                            y = 0

Therefore, coordinates of R are (-7,0)
