Write the equation of a line in slope-intercept form that passes through the point (1, 2) with a slope of 3.

\begin{tabular}{l}\hline \multicolumn{1}{|c|}{ Evaluating and Solving Exonential Functions } \\ \hline TabaSue invested 17,950 dollars in a savings account that paid \( 4.9 \% \) interest compounded annually. Write \\ the exponential equation \( A \) that represents TabaSue's investment where \( A \) is the accrued value of her \\ savings and \( t \) is the time of the investment in years. \\ \( A=\square \) \\ \hline Determine how much money TabaSue will have after 18 years. \\ Answer: After 18 years, TabaSue will have \\ to the nearest penny/cent.) \\ \hline Determine how long it will take for TabaSue's investment to double. \\ Answer: TabaSue's investment will have doubled in value after \\ the nearest tenth.) \end{tabular}

6. \( \quad f(x)=\sqrt{2 x+4}, \quad g(x)=\sqrt{2 x+4} \)

Find the slope of the line that goes through the given points. \( (9,-3) \) and \( (9,-4) \)

Solve: \( 9(-a-6)-37=36 a-1 \)

Simplify. \[ \frac{-5 \frac{1}{3}}{\left(\frac{4}{9}\right)^{2}} \]
