Question

The co-ordinates of the foot of perpendicular from the point (2, 3) on the line x + y – 11 = 0 are

• A. (– 6, 5)
• B. (5, 6)
• C. (– 5, 6)
• D. (6, 5)

Answer 1

Answer: (B)

(5, 6)

Answer 2

x + y – 11 = 0 ….(i)

$\frac { \beta - 3 } { 1 }$= –$\frac { \{ 2 + 3 - 11 \} } { \left( 1 ^ { 2 } + 1 ^ { 2 } \right) }$

Ž a = 5, b = 6

Hence M (5, 6)
