Final answer:
The slope of the line y = -1/2x - 5/8 is -1/2.
Step-by-step explanation:
To find the slope of the line y = -1/2x - 5/8, we can see that the equation is already in slope-intercept form (y = mx + b). The slope (m) is the coefficient of x, which is -1/2. Therefore, the slope of the line is -1/2.
