Write an equation in the form \( y=m x+b \) of the line that is described. The \( y \)-intercept is -9 and the line is parallel to the line whose equation is \( 5 x+y=6 \).

Give the domain of \( (x)=\frac{x+2}{2 x^{2}-5 x-18} \) using interval notation The domain of \( f(x) \) is:

3. \( x^{2}-25=0 \)

Solve the inequality. Graph the solution. \( \begin{array}{lll}\text { (7) } 5.8 y+5<3 & \text { 6. } 3 p+2 \geq-10 & \text { 7. } 2>8-\frac{4}{3} h \\ \text { 8. }-2>\frac{m}{6}-7 & \text { 9. }-1.2 b-5.3 \geq 1.9 & \text { 10. }-1.3 \geq 2.9-0.6 r\end{array} \)

\begin{tabular}{l|l|}\hline 2. Explain to someone who missed class how you would write \( (3-5 i)(-2+4 i) \) in the form \( a+b i \), \\ where a and b are real numbers. \end{tabular}

What are \( a \) and \( b \) when you write \( \sqrt{-16} \) in the form \( a+b i \), where \( a \) and \( b \) are real numbers?
