Question
Let PS be the median of the triangle with vertices P (2, 2), Q (6, -1) and R (7, 3), The equa tion of the line passing through (1, -1) and parallel to PS is
Options
A.2x - 9 y - 7 = 0
B.2x - 9 y -11 = 0
C.2x + 9 y -11 = 0
D.2x + 9 y + 7 = 0
Solution
Since, S is the mid point ofQ annd R.
∴
Now, slope of PS
Now, equation of the line passing through
(1, -1) and parallel to PS is
y + 1 = -
⇒ 2x + 9 y + 7 = 0
∴
Now, slope of PS
Now, equation of the line passing through
(1, -1) and parallel to PS is
y + 1 = -
⇒ 2x + 9 y + 7 = 0
