If the lines giviven by x-1 2 = y-1 -5 = z-1 2 and x+2 = y+3 = z+5 1 are parallel, then the value

Options

  1. A-2 5
  2. B2 5
  3. C5 2
  4. D-5 2

Correct answer

D. -5 2

Step-by-step solution

(A) Line x-1 2 = y-1 -5 = z-1 2 has direction ratios 2 ,-5,2 Line x+2 = y+3 , z+5 1 has direction ratios , , 1 Since lines are parallel, 2 = -5 = 2 1 = -5 2
