The two main ways of graphing and finding points on a graph are using the T-table method (T2) and the coordinate plane method (R). Let’s explore each method in detail:

1. T-table method (or T2):
In this method, we create a table (often referred to as a T-table) with two columns. The first column represents the independent variable (usually denoted by x) and the second column represents the dependent variable (usually denoted by y).
To find points on the graph, we select values for the independent variable (x) and substitute them into the given equation or relationship to calculate the corresponding values of the dependent variable (y). We then record these values in the table. Typically, at least two or three values are chosen to ensure accuracy.
Once we have a set of points (x, y) from the T-table, we can plot them on the graph by locating the x-value on the x-axis and the y-value on the y-axis. By connecting these points, we obtain the graph of the equation or relationship.

2. Coordinate plane method (or R):
In this method, we use the Cartesian coordinate system, which consists of a horizontal x-axis and a vertical y-axis intersecting at the origin (0, 0). Each point on the graph can be represented by an ordered pair (x, y) where x is the horizontal distance from the y-axis (positive to the right and negative to the left) and y is the vertical distance from the x-axis (positive upward and negative downward).
To find points using this method, we analyze the given equation or relationship and identify values of x that correspond to certain values of y. We then plot these points on the coordinate plane by locating the x-value on the x-axis and the y-value on the y-axis. By connecting these points, we obtain the graph of the equation or relationship.

Both methods are useful for graphing and finding points, but they differ in terms of how the points are represented and plotted. The T-table method is beneficial when we have a specific equation or relationship and want to generate points systematically, while the coordinate plane method allows for a visual representation of the graph and provides a clearer picture of the relationship between the variables.
