Correct Answer:
D. On the y-axis
In a Cartesian coordinate system, a point is represented by (x, y). The x-axis is the horizontal line where y=0, and the y-axis is the vertical line where x=0. Quadrants are defined by positive or negative x and y values.
- For the point (0, -7), the x-coordinate is 0.
- Any point with an x-coordinate of 0 lies directly on the y-axis.
- Since the y-coordinate is -7, it lies on the negative portion of the y-axis.
Therefore, option D is correct. Options A and B are incorrect as quadrants require non-zero x and y values. Option C is incorrect because the y-coordinate is not 0.
