Question

Which quadrant does (4, 0) lie?

Answer 1

It is on the positive x axis; the boundary between the first and fourth quadrant

Explanation:

The first quadrant has both positive x, and y coordinates. The fourth quadrant has positive x coordinates but negative y coordinates. The given point is on the boundary between these quadrants where the x coordinates are positive and the y coordinate is always 0; it is called the positive x axis.
