Inequality 1

Understanding the INEQUALITY Many mathematical techniques lend themselves to shortcuts. Sometimes these shortcuts are great and other times they seem to be "too tricky" to make sense when the same type problem needs attention later. One particular case is graphing an Open Sentence that is an INEQUALITY. For example: Graph the Solution Set for   " 5 <  x " Some students are taught to always have the "X" on the left so that the >  or < will point in the direction of the shaded solution. This requires the student to sometimes "SWITCH" the direction that the inequality sign points. (This switching only occurs when "X" is on the RIGHT SIDE!) so "5 < x" becomes " x > 5 " the graph is  ... The idea of 1) moving the x to the LEFT, 2) switching the direction of  " < "  to " > " and then 3) pointing the arrow of the graph in the direction of ">" does produce a correct...
