If the co-ordinates of the point in which the line joining the points (3,5,-7) and (-2,1,8) is intersected by the plane y z is [ a , 13 ~b , c ] , then (a+b-c)=

Options

  1. A2
  2. B3
  3. C4
  4. D5

Correct answer

B. 3

Step-by-step solution

Ratio =- ( 3 -2 )= 3 2 Required co-ordinates of the points are aligned & [ 6-6 5 , 10+3 5 , -14+24 5 ]= (0, 13 5 , 2 ) . & a+b-c=0+5-2=3 aligned
