What is the equation to the straight line passing through (a, b, c)...

What is the equation to the straight line passing through (a,b,c)(a, b, c) and parallel to zz-axis?

Options

  1. Ax−a1=y−b0=z−c0\frac{x-a}{1}=\frac{y-b}{0}=\frac{z-c}{0}
  2. Bx−a0=y−b0=z−c1\frac{x-a}{0}=\frac{y-b}{0}=\frac{z-c}{1}
  3. Cx−a0=y−b1=z−c0\frac{x-a}{0}=\frac{y-b}{1}=\frac{z-c}{0}
  4. Dx−a0=y−b1=z−c1\frac{x-a}{0}=\frac{y-b}{1}=\frac{z-c}{1}

Correct answer

B. x−a0=y−b0=z−c1\frac{x-a}{0}=\frac{y-b}{0}=\frac{z-c}{1}

Step-by-step solution

The correct answer is option B.
