how to graph inequalities in a number line????
@cherry2012 suppose you have ab inequality \[x >6\] |dw:1342499947409:dw| the open circle above the line x=6 indicates that x=6 is not included
|dw:1342500082083:dw|if we had \[x\ge 6\] we'd indicate with a filled circle
Do you understand this @cherry2012 ?
yes and how do you know to put a line to the right or left after you have graphed it?
if x> 6 line comes to the right if we had x<6, then line will come to left as numbers left of 6 are less than 6
