## Abstract

In chapter 9 we investigated the problem of finding the equation of a straight line given the graph of the line. In practice we often need to reverse this step — to draw a graph of a straight line whose equation is given. From our present knowledge this is a relatively elementary operation. Let us approach the problem via an example: suppose we wish to draw a graph of the line *y* = ¾*x* + 2.
