The slope-intercept form of an equation is written as y = mx + b, where m represents the slope and b represents the y-intercept. In the given equation, we can rearrange it to get -2y = -4x + 8, then divide both sides by -2 to isolate y and get y = 2x - 4. This means that the slope is 2 and the y-intercept is -4.

Option A, y = 4x + 8, is incorrect because it has the wrong slope. Option B, y = 4x - 8, is incorrect because it has the wrong y-intercept. Option C, y = 2x + 8, is incorrect because it has the wrong y-intercept. Therefore, option D, y = 2x - 8, is the only correct answer.
