If A(2,-1) and B(6,5) are two points the ratio in which the foot of the perpendicular from (4,1) to A B divides it, is
Options
- A8: 15
- B5: 8
- C-5: 8
- D-8: 5
Correct answer
B. 5: 8
Step-by-step solution
Let P(4,1) and P D A B . Equation of P D is 2 x+3 y-11=0 D divides A B in the ratio aligned & -(2 2+3 -1-11) 2 6+3 5-11 &= 10 16 &= 5: 8 aligned
