Question 232763
<font face="Garamond" size="+2">


A number line.  Filled in dot at -4.  Filled in dot at 10.  Heavy line connecting the two dots.


The dots are filled in because there are square brackets on each end of the interval meaning the endpoints are included.  Contrast this with parentheses on the end of the interval which excludes the end point, and the graph would be an open circle rather than a filled in dot.
