The following are terms you must know when working with graphs and direct variations. Without being able to define these terms, you may not be able to complete this area of Algebra successfully.

continuous can be drawn without picking up your pencil from the paper

dependent variable in a formula, it's the variable whose value always depends on the value of the other variable(s)

direct variation a situation in which as one variable increases in absolute value, so does the other

discontinuous cannot be drawn without picking up your pencil from the paper

discrete made up of unconnected points

independent variable in a formula, this variable determines the value of the other variable(s)

inverse variation a situation in which as one variable increases in absolute value, the other variable(s) decrease in absolute value

rate of change the slope of a line which also shows how x determines y or how y determines x
