Answer:
y = -1/2x -2
Step-by-step explanation:
The slope-intercept form of the equation for a line is ...
y = mx + b
Comparing this to the equation you are given, you find that the given equation describes a line with a slope of -1/2 and a y-intercept of +6. The parallel line will have the same slope, so m=-1/2.
The given point is the y-intercept of the line you want, so you can use that y-value directly as the "b" in the equation you want:
y = -1/2x -2
