The slope of the line shown in this graph include the following: B. slope = 1/2.
In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = rise/run

From the information provided in the graph, we have the following points on the line:
Points = (2, -2).
Points = (6, 0).
By substituting the given points into the formula, we have;
Slope, m = (0 + 2)/(6 -2)
Slope, m = 2/4
Slope, m = 1/2
Missing information:
