Answer
negative
Explanation
Let's find the slope of our line using the slope formula:

where
is the slope of the line
are the coordinates of the first point on the line
are the coordinates of the second point
From the graph we can get the points (-2, 1) and (2, -1), so
,
,
, and
. Let's replace the values in our formula to find
:






The slope of the graph of the linear function is
; since
is a negative number, the slope of the graph is negative.
