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

To find the distance of a point from the y-axis, we need to consider the x-coordinate of the point. The distance of any point \((x, y)\) from the y-axis is the absolute value of its x-coordinate.

Given the point \(P(3a, 4a)\), the x-coordinate is \(3a\). Therefore, the distance of point \(P\) from the y-axis is the absolute value of \(3a\):

\[\lvert 3a \rvert = 3a\]

Thus, the correct answer is:

\(3a\)
