In graphical linear programming, the objective function is represented by a family of parallel lines (iso-profit or iso-cost lines), which are linear. This means that for any given value of the objective function, there is a line (part of a family of such lines) that represents all the combinations of decision variables that result in that value. These lines are parallel because the slope of the objective function (which represents the rate of change between the decision variables) remains constant.
