A labelled graph of three different points with a y-coordinate of -4 is shown on the coordinate plane in the image below.
In Euclidean Geometry, an ordered pair is a pair of two elements (data points) that is written in a fixed order and within parentheses as (x, y), which represents the x-coordinate and the y-coordinate of any graph respectively.
In order to plot the coordinates of each of the points, you would have to move to the right or left on the x-axis and then move up or down on the y-axis depending on the ordered pairs.
In this exercise, a list of possible three different points with a y-coordinate of -4 are as follows;
A = (0, -4)
B = (2, -4)
C = (4, -4)
In conclusion, we would use an online graphing tool to plot the points in each quadrant by placing the ordered pair or coordinates on the coordinate plane.
