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 the line connecting the points \((-4, 7)\) and \((4, 8)\), you can use the formula for slope (m):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, \((x_1, y_1) = (-4, 7)\) and \((x_2, y_2) = (4, 8)\).
Plugging in the values:
\[ m = \frac{8 - 7}{4 - (-4)} = \frac{1}{4 + 4} = \frac{1}{8} \]
So, the slope of the line is:
\(\frac{1}{8}\)
The correct response is:
