Exercise 39 Page 267

The given equation says that the y-values are one and a half more than x. By substituting some arbitrary values for x, we can simplify and determine the corresponding values of y, which we can use to form ( x, y) coordinate pairs. We will do this a few times to make a table of values for the given function rule.

Let's plot these three points on a coordinate plane.

By connecting all of our points with a line, we form the graph of the function rule.
