Graph the ordered pairs and draw the line through them.
Let's do these things one at a time.
Making a Table of Values
To make a function table, we will select some values of x which will be part of our domain. Then, we will substitute these values for x to find the corresponding values of y. These x- and y-values will create a set of ordered pairs.
x
4x
y
(x,y)
- 1
4( - 1)
- 4
( - 1, - 4)
0
4( 0)
0
( 0, 0)
1
4( 1)
4
( 1, 4)
We found three ordered pairs that lie on the graph of our function.
Graphing the Ordered Pairs and Drawing the Line
Next, we will graph the ordered pairs and connect them with a straight line.
