How to Write Equations That Represent Data Tables or Charts - Mathematics is all about determining and representing relationships. The relationships identify the impact of one variable over the other. For instance, to describe the relationship between a person's height and weight, we need to express in the form of an equation. The most commonly used ways to represent a relationship between x and y values on a coordinate plane are using a table, a graph, or an equation. In this description, we shed light on how to represent data tables or charts in the form of equations. A data table or chart shows a list of the values for two variables; an independent variable x, compared with the values of a dependent variable, y. To determine the relationship between these two variables, an equation can be used. Because if you know the equation, you can easily determine the answers. Look at the table below that has values of both x and y variable. You must determine how both the costs are related and then form an equation that expresses their relationship. (x, y), value 1 (-2, -1), value 2 (-1, 0), value 3 (0, 1), value 4 (1, 2). Looking at the values of x and y, you can easily form a relationship between the values. It's easy to determine that each y-value is one more than the value of x. Therefore, the equation that describes this relationship is y = x + 1.
