Concept Introduction:

Independent and Dependent Variable: There are two main variables for constructing a graph namely, independent variable and dependent variable. The independent variable is that variable that increases or decreases on its own and a dependent variable is that variable that changes depending upon the changes in an independent variable.

Slope of line: The slope of a line represents the change in the value on y-axis per unit value on x-axis. The slope of a line is a measure of steepness of the line.
