Answer:
1/2
Step-by-step explanation:
It usually works well to compute the slope from coordinates where the graph crosses grid line intersections. We can identify two of those as ...
(-1, 3) and (1, 4)
The slope formula tells you the slope is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -3)/(1 -(-1)) = 1/2
The slope of the line is 1/2.

Additional comment
The y-intercept is 3 1/2.
An equation for the line could be ...
y = 1/2x + 3 1/2 . . . slope-intercept form
x -2y = -7 . . . . . . . . standard form
