the inequality sign will only change in an equation if you are multiplying or dividing by a negative number...
for example if you have the equation -1x+2>3 you would subtract by 2
you would have -1x>1
the next step is -1x>1
-1 -1
your dividing by -1 so the sign flips from greater than to less than (it can go less than to greater than too) and your final answer would be x<-1

Does an inequality change when you multiply by a negative?
Yes you have to flip the sign.
What way does an inequality sign face when it is greater than or equal to?
The inequality sign opens towards the bigger number.
What are the critical features of an inequality?
An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).
How do you know weather to shade above or below the line when graphing an inequality on the coordinate plane?
If the inequality has a > or ≥ sign, you shade above the line. If the inequality has a < or ≤ sign, you shade below it. Obviously, just an = is an equation, not an inequality.
When graphing a linear inequality the first step is to replace the inequality symbol with a sign?
