# How do you graph y=-x+6 by plotting points?

##### 1 Answer

Pick a few values for $x$ (I would suggest ones that make $y = - x + 6$ easy to evaluate).
Plot the resulting $\left(x , y\right)$ value pairs on the Cartesian plane.
Draw line through the points.

#### Explanation:

For example, choosing $x \in \left\{- 1 , 0 , + 1\right\}$
gives
color(white)("XXX"){: (ul(x),color(white)("XX"),ul(y=-x+6)), (-1,,7),(0,,6),(+1,,5) :}
results in the pairs:
$\textcolor{w h i t e}{\text{XXX}} \left(- 1 , 7\right) , \left(0 , 6\right) , \left(1 , 5\right)$

Plotting these and drawing a line through these points should look like:
