The distance of the point P(-3,4,5) from yz plant is

Options

A. 3 units
B. 4 units
C. 5 units
D. none of these

Answer

To find the distance of the point P(-3, 4, 5) from the yz-plane, we can follow these steps:

### Step 1: Understand the yz-plane
The yz-plane is defined by the equation x = 0. This means that any point on the yz-plane has an x-coordinate of 0.

### Step 2: Identify the coordinates of point P
The coordinates of point P are given as (-3, 4, 5). Here, the x-coordinate is -3, the y-coordinate is 4, and the z-coordinate is 5.

### Step 3: Use the distance formula
The distance of a point (x, y, z) from the yz-plane can be calculated using the formula:
\[ \text{Distance} = |x| \]
This is because the distance from the yz-plane is simply the absolute value of the x-coordinate of the point.

### Step 4: Substitute the x-coordinate of point P
For point P(-3, 4, 5), the x-coordinate is -3. Therefore, we calculate:
\[ \text{Distance} = |-3| = 3 \]

### Step 5: Conclusion
The distance of the point P(-3, 4, 5) from the yz-plane is 3 units.
