A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position. The correct option is D.
What are coordinates?
A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
For a function to be even, the graph of the function should be such that it should be symmetrical about the x-axis. Therefore, the points of the graph will be the opposite.
The 7 points of option D can be plotted as shown below, which is symmetrical about the X-axis. Hence, the correct option is D.
