AA. 1 Is \( (x, y) \) a solution to the linear equation? \( 5 B D \) Does the point \( (2,0) \) satisfy the equation \( y=7 x \) ?

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

\( - 8.3 + x = - 12.5 \quad [ - 5.2 ] \)

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

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

Jason earns an hourly wage of \( y \) dollars. If he works \( h \) hours in a week, write a linear expression representing his weekly earnings.
