The distance of the point P(2, 3) from the x-axis is

1. 2 units

2. 3 units

3. 1 unit

4. 5 units

The distance between the point P(2, 3) and x-axis can be determined by assuming a point A(2, 0) on x-axis.

By distance formula,

$\Rightarrow d = \sqrt{(x$2 - x1)^2 + (y2 - y1)^2} \\[1em] \Rightarrow AP = \sqrt{(2 - 2)^2 + (3 - 0)^2} \\[1em] \Rightarrow AP = \sqrt{0 + 3^2} \\[1em] \Rightarrow AP = \sqrt{9} \\[1em] \Rightarrow AP = 3 \text{ units}.

Hence, Option 2 is the correct option.
