The co-ordinates of the foot of the perpendicular from the point (1,2) on the line x-3 y+7=0 are

Options

  1. A( 4 5 , 13 5 )
  2. B(-13,-2)
  3. C( -13 5 , -2 5 )
  4. D(2,3)

Correct answer

A. ( 4 5 , 13 5 )

Step-by-step solution

aligned & x-1 1 = y-2 -3 = -(1-3 2+7) 1^2+(-3)^2 & x-1 1 = y-2 -3 = -2 10 & x= 4 5 and y= 13 5 & ( 4 5 , 13 5 ) aligned
