The equation of a line through the point (1, 2) whose distance from the point (3, 1) has the greatest possible value is-
A
x + 2y = 3
B
y = 2x
C
y = x + 1
D
x + 2y = 5
Answer
y = 2x
Explanation
Solution
Line at greatest distance from (3, 1) points will be perpendicular to line joining given two points (1, 2) and
(3, 1).
