Final answer:
The term representing the vertical position on a coordinate system for a given ordered pair is the y-value. In a Cartesian plane, (x, y) denotes an ordered pair, with y indicating the vertical position. In physics graphs of displacement versus time, the y-axis signifies displacement, and slope of the line gives velocity.
Step-by-step explanation:
The term that represents the vertical position on a coordinate system for a given ordered pair is the y-value. In a coordinate system or a Cartesian plane, the ordered pair is typically represented as (x, y), where x represents the horizontal position (the x-coordinate) and y represents the vertical position (the y-coordinate). In the context of a graph where the equation is in the form y = mx + b, the slope (m) indicates how steep the line is and the y-intercept (b) indicates the point where the line crosses the y-axis.
In physics, specifically when analyzing displacement versus time graphs, the y-axis often represents displacement (the vertical position), and the x-axis represents time (the horizontal position). The slope of such a graph would provide the velocity of the object, and the y-intercept would represent the initial displacement. If the slope is positive, it indicates that as time increases, the displacement also increases at a rate determined by the slope.
