Solve the inequality (on the final you will also need to graph)

 $\left|x-9\right|\le9$  

•  $-6<x\le4$  

•  $0\le x\le18$  

•  $x<-6\ or\ x\ge4$  

•  $-27\le x\le9$  

Write the equation in slope-intercept form for the line that passes through (4, 3) and is parallel to

 $y=\frac{1}{4}x$  

•  $y=-4x+19$  

•  $y=\frac{1}{4}x+3$  

•  $y=2x+\frac{1}{4}$  

•  $y=\frac{1}{4}x+2$  

Choose the graph of the system of inequalities

 $y>-2x-1$ 
  $y\le-\frac{1}{2}x+2$
