Exercise 6 Page 371

Next, we find 0 on the y-axis and follow this grid line until it collides with the grid line from our x-coordinate. The y-coordinate 0 tells us that the point lies on the x-axis.

The point ( -5, 0) lies on the point at which these two grid lines intersect. Now we want to describe the location of this point. Recall what we know about the quadrants of a coordinate plane. The coordinate plane is divided into four quadrants by the x- and y-axes.

The y-coordinate of the point (-5,0) is 0. The part of the coordinate plane where one of the coordinates is 0 is the axes. The axis where the y- coordinate is 0 is the x-axis. Therefore, the point is located on the x-axis.
