# How do you graph y=-x+2 by plotting points?

$\left(0 , 2\right) \left(1 , 1\right) \left(2 , 0\right) \ldots \ldots . .$

#### Explanation:

$y = - x + 2$

Choose x-values and use the given equation to work out y-values.
if...
$x = 0 , y = 2 \rightarrow \left(0 , 2\right)$
$x = 1 , y = 1 \rightarrow \left(1 , 1\right)$
$x = 2 , y = 0 \rightarrow \left(2 , 0\right)$

so plot the points $\left(0 , 2\right) , \left(1 , 1\right) , \left(2 , 0\right)$ on a grid and join them with a straight line.
