A point on the line (x-1)/(1)=(y-3)/(2)=(z+2)/(7) has coordinates

A point on the line \frac{x-1}{1}=\frac{y-3}{2}=\frac{z+2}{7}$ has coordinates

Options

  1. A(3,5,4)(3,5,4)
  2. B(2,5,5)(2,5,5)
  3. C(−1,−1,5)(-1,-1,5)
  4. D(2,−1,0)(2,-1,0)

Correct answer

B. (2,5,5)(2,5,5)

Step-by-step solution

x−11=y−32=z+27\frac{x-1}{1}=\frac{y-3}{2}=\frac{z+2}{7} Verify from options Only (2,5,5)(2,5,5) satisfies the above equation.
