Question

What is the point called where horizontal and vertical lines meet

Answer 1

The horizontal line is known as the x-axis and the vertical line is called the y-axis. These axes intersect to form four quadrants. Because the x and y axes are perpendicular to one another, they intersect only once, in a place called the origin.

Answer 2

The point where horizontal and vertical lines meet (in general) is called the point of intersection of the two lines.

This point in terms of graph we call as the origin.
