How to Determine Linear Table Worksheets
Linear data input to a chart consists of two variables: x and y. For every x value, there is a corresponding y value. For example, if you're conducting a science experiment and need to record numerical data in a table, you can use this table to give you insight into the relationship between two values of a function.

Look at the left-hand column of your table of values. Locate the corresponding x position on the graph or input it into your graphing calculator's graph function.

Look immediately to the right of this value to find its y value. Plot it on the graph. For example, if you have values of 2 and 5, the point is located two spaces along the x axis and five spaces up the y axis.

Repeat this process for all the points on the table and plot each point on the graphing paper, drawing a line from one point to the next, or finish filling in the table on your calculator and press the "Graph" button.

Note the general slope of the configuration. Two types of linear relationships exist: direct and inverse. If x and y have a direct relationship, y increases as x does. In an inverse relationship, y decreases as x increases.
