Question 1093718
y > -1 or y <= -5 
<pre>
It's better to swap them so the numbers will go from smallest
to largest,

          {{{matrix(1,7,
y,""<="",-5,or,y,"">"",-1)}}}

Draw the number line graph:

<============&#9787;-----------&#9786;=============================>
-9 -8 -7 -6 -5 -4 -3 -2 -1  0  1  2  3  4  5  6  7  8  9

    {{{matrix(1,3,

matrix(1,5,"(",-infinity,",",-5,"]"),
U,
matrix(1,5,"(",-1,",",infinity,")") )}}}

Interval notation is just an abbreviation for the graph on a
number line.

If the graph goes all the way to the left, put  
    {{{matrix(1,2,"(",-infinity)}}} on the left end of the
interval notation

If the graph goes all the way to the right, put
                           {{{matrix(1,2,infinity,")")}}} on the right end
of the interval notation
