Place the steps for solving and graphing the inequality in the correct order.
1-2a>5
Draw an arrow from the boundary point pointing to the left.
Draw an open boundary point at -2 on a number line.
Divide both sides by -2 (and remember to flip the inequality symbol) to arrive at a<-2.
Subtract 1 from both sides to arrive at -2a>4.
Solve the inequality.
