The co-ordinates of the foot of the perpendicular from \((0,0)\) upon the line \(x+y=2\) are
- A \((2,-1)\)
- B \((-2,1)\)
- C \((1,1)\)
- D \((1,2)\)
Answer & Solution
Correct Answer
(C) \((1,1)\)
Step-by-step Solution
Detailed explanation
Hints : Let \(\mathrm{P}\) be the foot of the perpendicular. P lies on a line perpendicular to \(x+y=2\). \(\therefore\) Equation of the line on which P lies is of the form : \(x-y+k=0\) But this line passes through \((0,0)\). \[ \therefore k=0 \] Hence, co-ordinates of P may be…
