Answer:
y-4=-2(x-2) and y=-2x+8
Step-by-step explanation:
y=-2x+8 is correct because the slope is correct and the y-intercept is 8 as stated
y-4=-2(x-2) is correct because it uses a point given in the correct way and the slope is also correct
2x+y=8 is also correct because it can be converted to slope intercept form as y=-2x+8
