The correct Answer is:
To solve the problem, we need to find the value of \( \lambda \) given that the perpendicular distance of the point \( (6, 5, 8) \) from the \( y \)-axis is \( 5\lambda \) units. ### Step-by-step Solution: 1. **Identify the Coordinates**: The point given is \( (6, 5, 8) \). Here, the \( x \)-coordinate is \( 6 \), the \( y \)-coordinate is \( 5 \), and the \( z \)-coordinate is \( 8 \). 2. **Understand the Distance from the \( y \)-axis**: The perpendicular distance of any point from the \( y \)-axis is determined solely by its \( x \)-coordinate. This is because the \( y \)-axis is defined by \( x = 0 \). Therefore, the distance from the point \( (x, y, z) \) to the \( y \)-axis is simply \( |x| \). 3. **Calculate the Distance**: For the point \( (6, 5, 8) \), the distance from the \( y \)-axis is: \[ \text{Distance} = |6| = 6 \text{ units} \] 4. **Set Up the Equation**: According to the problem, this distance is also equal to \( 5\lambda \). Therefore, we can write: \[ 6 = 5\lambda \] 5. **Solve for \( \lambda \)**: To find \( \lambda \), we divide both sides of the equation by \( 5 \): \[ \lambda = \frac{6}{5} \] ### Conclusion: Thus, the value of \( \lambda \) is \( \frac{6}{5} \). ---
