Make a function table to obtain ordered pairs.
To graph the equation y= 12x+5, we will follow two steps.
To make a table of Values, we will select some values of x. 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 | 1/2x+5 | y | (x,y) |
|---|---|---|---|
| 0 | 1/2( 0)+5 | 5 | ( 0, 5) |
| 1 | 1/2( 1)+5 | 11/2 | ( 1, 11/2) |
| 2 | 1/2( 2)+5 | 6 | ( 2, 6) |
| 3 | 1/2( 3)+5 | 13/2 | ( 1, 13/2) |
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 equation. The ordered pairs corresponding to any points on the line are solutions of the equation y= 12x+5.
