Find the slope, if it exists, of the line containing the pair of points. \[ (-9,-12) \text { and }(-14,-15) \] Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The slope is \( \square \). (Type an integer or a simplified fraction.) B. The slope is undefined.

[b] Simplify to the simplest form : \( \sqrt{125}-\sqrt[3]{250}+\frac{1}{2} \sqrt[3]{16}+\sqrt{20} \)

A. \( \frac{3}{5}+\frac{7}{11}=\frac{\square}{55} \)

W1. Wite a number in the box to make itis correct. \[ \frac{3}{5}<\frac{\square}{100}<0.7 \]

Express the repeating decimal number as a quotient of two integers. \( 4 . \overline{45} \) \( 4 . \overline{45}=\square \) (Simplify your answer. Type an improper fraction.)

\( \begin{array}{ll}\text { a) } 3 \sqrt{12}-5 \sqrt{27}+\sqrt{243}-\frac{1}{5} \sqrt{75} & \text { b) } \sqrt{14+\sqrt{7-\sqrt[4]{81}}}\end{array} \)
