Answer 3

Finding Parallel Lines from the Given Equations

To determine which equations represent parallel lines, we need to compare their slopes. Two lines are parallel if and only if their slopes are equal.

Let's analyze each equation and find the slopes:

1. y = 3x - 2: The slope of this line is 3. 2. y = 2x + 1: The slope of this line is 2. 3. y = -x + 1: The slope of this line is -1. 4. y = -2x: The slope of this line is -2. 5. y = 5 + 3x: The slope of this line is 3. 6. y = 2x: The slope of this line is 2. 7. y = 1 - 2x: The slope of this line is -2.

From the given equations, the pairs of parallel lines are:

- y = 3x - 2 and y = 5 + 3x (both have a slope of 3). - y = 2x + 1 and y = 2x (both have a slope of 2). - y = -x + 1 and y = 1 - 2x (both have a slope of -2).

Therefore, the parallel lines are:

1. y = 3x - 2 and y = 5 + 3x. 2. y = 2x + 1 and y = 2x. 3. y = -x + 1 and y = 1 - 2x.
