Final answer:
The equation of the horizontal line that passes through the point (-2, -7) is y = -7.Correct option is A.
Step-by-step explanation:
horizontal line, we need to identify that the line has a slope of 0. In this case, we are given the point (-2, -7) that the line passes through. Since the line is horizontal, its slope is 0. Therefore, the equation of the line is y = -7.
