Question 24005
1. let number be x


so, 
a) greater than -6 is x>-6 or -6<x... the inequality still says x is LARGER than the -6.
and 
b) less than 6 is x<6


Written together, we have -6<x<6


2. 
at least -6 is x>=-6 since "at least" means it can be equal to -6
and
at most 3 is x<=3 since "at most" means it can equal 3.


Written together, we have -6<=x<=3


As for graphing them...


you need a straight line running from -6 to +6 in 1. and from -6 to +3 in 2.


You use a circle to highlight the ends. The circle is either hollow or solid (colour it in) depending upon if you have "<" or "<=" etc. I cannot remember which way round it is...your notes will explain the difference.
