Use the image to answer the question.
A coordinate plane shows four quadrants with both the x-axis and the y-axis ranging from negative 10 to positive 10 in increments of 2. Two points are plotted and joined by a line. The plotted points are as follows: left parenthesis negative 4 comma 7 right parenthesis, left parenthesis 4 comma 8 right parenthesis. A line connects the two plotted points and extends beyond the points in both directions.
Find the slope of the line given its graph.

To find the slope of a line, we can use the formula:
slope = change in y / change in x
For the given graph, we can identify two points: (-4, 7) and (4, 8).
So, the change in y = 8 - 7 = 1
The change in x = 4 - (-4) = 8
Using the formula, the slope of the line is given by:
slope = 1/8
Therefore, the correct answer is:
