To determine the slope of the graphed line, we can use the formula:
Slope (m) = (change in y) / (change in x)
Given the points (-8, 0) and (0, 4), the change in y is 4 - 0 = 4, and the change in x is 0 - (-8) = 8.
So, the slope of the graphed line is 4/8, which simplifies to 1/2. Therefore, the number that best represents the slope of the line is 1/2.
