Question
complete the ordered pairs so that each is a solution to the equation. then choose two of the points to graph the equation.
y = -5x + 2
find three ordered pairs by completing the table.
| x | -2 | 0 | 2 |
| y | □ | □ | □ |
Step1: Substitute $x=-2$ into equation
$y = -5(-2) + 2 = 10 + 2$
Step2: Calculate $y$ for $x=-2$
$y = 12$
Step3: Substitute $x=0$ into equation
$y = -5(0) + 2 = 0 + 2$
Step4: Calculate $y$ for $x=0$
$y = 2$
Step5: Substitute $x=2$ into equation
$y = -5(2) + 2 = -10 + 2$
Step6: Calculate $y$ for $x=2$
$y = -8$

The completed table is:
| $x$ | $y$ |
|---|---|
| 0 | 2 |
| 2 | -8 |
The ordered pairs are $(-2, 12)$, $(0, 2)$, $(2, -8)$. To graph, plot these points and draw a straight line through them.
