2) What is the quotient when \( x^{3}-2 x^{2}-9 \) is divided by \( x-3 \) ? \( \begin{array}{ll}\text { A) } x^{2}+x-6 & \text { B) } x^{2}-5 x+6\end{array} \)

2. Suppose y varies directly with \( x \). If \( x \) is 30 when \( y \) is 10 , what is \( x \) when \( y \) is 9 ? (D) 3 (1) 27 (C) 29 (D) \( \frac{300}{9} \) 3. Which equation represents a line with slope -2 and \( y \)-intercept 3 ? (D) \( 3 y=x-2 \) (C) \( 3 y=-2 x+1 \) (H) \( y=2 x-3 \) D \( y=-2 x+3 \) 8. What is the vertex of \( y=|x|-5 \) ? (A) \( (5,0) \) (B) \( (-5,0) \) (C) \( (0,5) \) (D) \( (0,-5) \) . The amount of a commission is directly proportional to the amount of a sale.
