Final answer:
To plot and label 5 different points with a y-coordinate of -4, all the points will lie on the x-axis.
Step-by-step explanation:
To plot and label 5 different points with a y-coordinate of -4, we can choose any 5 points on the x-axis with -4 as the y-coordinate. Let's say we choose the points (1, -4), (2, -4), (3, -4), (4, -4), and (5, -4). When we plot these points on a graph, we notice that all the points lie on the x-axis. Therefore, the correct answer is A. All points lie on the x-axis.
