Answer:

The equation of the line passing through the point (-2,2) and parallel to the line 2x+y=1 is y = -2x - 2.

Explanation:

To find the equation of the line passing through the point (-2,2) and parallel to the line 2x+y=1, we first need to determine the slope of the given line.

The slope of the given line can be found by rearranging the equation in slope-intercept form y=mx+b, where m is the slope and b is the y-intercept.

2x+y=1

y = -2x + 1

So the slope of the given line is -2

Since the line we are looking for is parallel to the given line, it must have the same slope of -2.

We can now use the point-slope form of the equation of a line to find the equation of the line passing through (-2,2) with a slope of -2:

y - y1 = m(x - x1)

where (x1,y1) = (-2,2) and m = -2

Plugging in these values, we get:

y - 2 = -2(x - (-2))

Simplifying the right side:

y - 2 = -2(x + 2)

Expanding:

y - 2 = -2x - 4

Adding 2 to both sides:

y = -2x - 2

So the equation of the line passing through the point (-2,2) and parallel to the line 2x+y=1 is y = -2x - 2.
