Final answer:
The equation of the horizontal line that passes through the point (-2, -1) is y = -1. This is because horizontal lines have a slope of 0, indicating no change in the y-value.
Step-by-step explanation:
The equation of the horizontal line that passes through the point (-2, -1) is y = -1. This is because a horizontal line has a slope of 0 and does not change in the y-value as x varies. The specific y-value where the line is located is the y-coordinate of the point (-2, -1). Hence, the equation of the horizontal line is simply the y-coordinate of that point, and the line will cross the y-axis at y = -1.
The equation of the horizontal line that passes through the point (-2, -1) is y = -1.
A horizontal line is a line that has a constant y-value regardless of the x-value. In this case, the y-value is -1 because the line passes through the point (-2, -1).
The equation y = -1 represents a horizontal line at a specific y-value of -1.
