Answer 2

Answer:

The distance is 4 units.

Step-by-step explanation:

The point is, P (-3, -4).

On drawing a straight line from this point to the x-axis the line will me the x-axis at X (-3, 0).

The distance formula is:

$d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

Compute the distance as follows:

$d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\=\sqrt{(-3-(-3))^{2}+(0-(-4))^{2}}\\=\sqrt{0+16}\\=\sqrt{16}\\=4$

Thus, the distance is 4 units.
