To find the distance between the points \((2, 3)\) and \((-4, -9)\), we can use the distance formula:

\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]

Where \((x_1, y_1) = (2, 3)\) and \((x_2, y_2) = (-4, -9)\).

Now we can plug in the values:

\[ d = \sqrt{((-4) - 2)^2 + ((-9) - 3)^2} \] \[ d = \sqrt{(-6)^2 + (-12)^2} \] \[ d = \sqrt{36 + 144} \] \[ d = \sqrt{180} \]

Now we can simplify \(\sqrt{180}\):

\[ d = \sqrt{36 \times 5} = \sqrt{36} \times \sqrt{5} = 6\sqrt{5} \]

Next, we can calculate \(6\sqrt{5}\):

Using \( \sqrt{5} \approx 2.236 \):

\[ d \approx 6 \times 2.236 \approx 13.416 \]

Rounding to the nearest hundredth, the distance is:

\[ \boxed{13.42} \]
