Exercise 41 Page 267

Substitute some arbitrary values for x to find their corresponding y-values.

Practice makes perfect

The given equation says that the y-values are six times 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.

x 6x y (x,y)
-1 6( -1) -6 ( -1, -6)
0 6( 0) 0 ( 0, 0)
1 6( 1) 6 ( 1, 6)

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.
