Final answer:
The slope-intercept form of the equation y = -1/2(x - 8) is y = -1/2x - 4.
Step-by-step explanation:
The slope-intercept form of an equation is given by the formula y = mx + b, where m represents the slope and b represents the y-intercept. In the given equation, y = -1/2(x - 8), we can rewrite it as y = -1/2x + 4. Therefore, the correct slope-intercept form of the equation is y = -1/2x + 4 (option b).
