Question

can we call the whole horizontal line as x axis including x axis and x' axis​

Answer 1

Answer:

Definition: A straight line on the coordinate plane where all points on the line have the same y-coordinate.

A horizontal line is one the goes left-to-right, parallel to the x-axis of the coordinate plane. All points on the line will have the same y-coordinate. In the figure above, drag either point and note that the line is horizontal when they both have the same y-coordinate.

A horizontal line has a slope of zero. As you move to the right along the line, it does not rise or fall at all. As you drag the points above, you can see that when the line is horizontal, the points both have the same y-coordinate, and the slope is zero.

The equation of a horizontal line is

y = b Where:

x is the coordinate of any point on the line

b is where the line crosses the y-axis (y intercept).
