Answer 2

Step-by-step explanation:

Since S is mid point of Q and R

∴S=( 7+6 , 3-1 )=( 13 , 1)

2 2 2

slope of PS =m y2 - y1 = 2 - 1. =

x2 - x1. = 2 - 13.

2

-2

Equation of the line passing through

(1,−1) and parllel to PS is

y − (−1) = -2. ( x - 1)

9

y + 1 = -2x + 2.

9

⇒9y + 9 + 2x − 2 = 0

⇒2x + 9y + 7 = 0
