The horizontal axis is represented by the x-axis and the vertical axis is represented by the y-axis. The point where the X and Y-axis intersect is known as the origin and is used as the reference point for the plane.
The x-axisrepresents the time of motion measured in seconds.
From the given graph we can deduce the following;
on the y-axis (vertical axis), the distance of the object's motion is being represented in miles.
on the x-axis (horizontal axis), the time of motion of the object is being represented.
the horizontal axis represents the time of motion because the object change position at different time which can be seen in the different colours of the letter A, B, C and D.
Thus, the we can conclude the x-axisrepresents the time of motion measured in seconds.
