# How do you find three different ordered pairs y=2x+1?

Nov 16, 2016

Pick $3$ arbitrary values for $x$ and evaluate for corresponding $y$ values to give $\left(x , y\right)$ pairs.

#### Explanation:

For example if I choose
$\textcolor{w h i t e}{\text{XXX}} x \in \left\{0 , 1 , 2\right\}$

{:(underline(x),color(white)("XX"),underline(y=2x+1)), (0,,color(white)("XXX")1), (1,,color(white)("XXX")3), (2,,color(white)("XXX")5) :}

Giving the ordered pairs
$\textcolor{w h i t e}{\text{XXX}} \left(0 , 1\right) , \left(1 , 3\right) , \left(2 , 5\right)$
