Graph the ordered pairs and draw the line through them.
Let's do these things one at a time. 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 into the function for x to find the corresponding values of y. These x- and y-values will create a set of ordered pairs.
x
x+3
y
(x,y)
- 2
( - 2)+3
1
( - 2, 1)
- 1
( - 1)+3
2
( - 1, 2)
0
( 0)+3
3
( 0, 3)
1
( 1)+3
4
( 1, 4)
We found four ordered pairs that lie on the graph of our function. Next, we will graph the ordered pairs and connect them with a straight line.
The line is the complete graph of the function. The ordered pairs corresponding to any points on the line are solutions of the equation y=x+3.
