Question

The distance of point \(P(3a, 4a)\) from y-axis is

• A. \(3a\)
• B. \(-3a\)
• C. \(4a\)
• D. \(-4a\)

Hint:

Distance from y-axis = \(|x|\), from x-axis = \(|y|\)

Answer 1

The Correct Option is A

Given:
Point \(P(3a, 4a)\)

Step 1: Understand what is asked
We need to find the distance of point \(P\) from the y-axis.

Step 2: Recall the distance formula from y-axis
The distance of any point \((x, y)\) from the y-axis is the absolute value of the x-coordinate.

Step 3: Identify the x-coordinate of point \(P\)
Here, the x-coordinate is \(3a\).

Step 4: Calculate the distance
Distance from y-axis = \(|3a| = 3a\) (assuming \(a > 0\))

Final Answer:
\[ \boxed{3a} \]
