Can you explain when we flip the inequality direction when solving inequalities.

We solve inequalities exactly like normal equations except for Dividing by a Negative Coefficient where we Change the inequality directionE.gx+2>4 is ... x>2 (ask second sim example)x-1>1 is ... x>23x<9 is ... x<3-3x>9 is ... x>31/2x<2 is ... x<4
Explanation of why this is dependent on interest/ability of student but emphasis placed on not being requiredUse Function graph to explain.
