Final answer:
The equation of the line parallel to y = -2 and passing through (-2, -7) is y = -7, as it must be horizontal and share the same y-coordinate of the point given.
Step-by-step explanation:
The equation of a line parallel to the line represented by y = -2 must have the same slope. Since the line given by y = -2 is a horizontal line with a slope of 0, any line parallel to it will also be horizontal and have no slope.
Therefore, the equation of the line we are looking for will also be a horizontal line and pass through the given point (-2, -7).
The equation of a horizontal line is given by y = constant, where the constant is the y-coordinate of any point on the line. Since we know our line passes through (-2, -7), the y-coordinate of any point on our line must be -7. Therefore, the equation of the line is y = -7.
