In order to graph -2.75≤ x ≤0 on the number line, we need to understand where x is placed, in this case the minimum value is -2.75 and the maximum is 0, also since the sign involves and equal then both minimum and maximum are included.
The same happens with the interval notation, since the maximum and minimum are included, then
[tex]\lbrack-2.75,0\rbrack[/tex]
