Final answer:
The question seems to involve matching coordinates with variables but lacks clear context. Generally, in Cartesian coordinates, points are denoted as (x, y), showing positions relative to the origin. Points can be plotted on a graph to represent the dependence of y on x in a function.
Step-by-step explanation:
The student's question appears to be about matching given coordinate points with variables, subsequent equations or rules that govern the assignment of these points to the variables. However, the provided information is fragmented and insufficient to identify a clear task or objective for these matches. Thus, it's difficult to offer a precise answer. However, I can explain how coordinates relate to variables in a general sense, which may help the student with identifying points on a graph, for instance.
Typically, in a Cartesian plane, a point is represented as (x, y) where x stands for the horizontal distance from the origin, and y stands for the vertical distance from the origin. The first number in the bracket is the x-coordinate and the second is the y-coordinate. If this relates to a function, each x value could correspond to one specific y value, illustrating the dependence of y on x.
A common high school mathematics exercise involves plotting these points on a graph to visualize the relationship between the variables. Points such as (1,5), (2,10), (3,7), and (4,14) can be plotted and connected to show the dependence of y on x, if indeed y is a function of x in the context of the question.
