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

$\text{see explanation}$

Explanation:

$\text{one way is to find the x and y intercepts, that is where }$
$\text{the graph crosses the axes}$

• " let x = 0, in the equation for the y-intercept"

• " let y = 0, in the equation for the x-intercept"

$x = 0 \to y = 0 + 2 = 2 \leftarrow \textcolor{red}{\text{ y-intercept}}$

$y = 0 \to x + 2 = 0 \to x = - 2 \leftarrow \textcolor{red}{\text{ x-intercept}}$

$\text{plot } \left(0 , 2\right) , \left(- 2 , 0\right)$

$\text{and draw a straight line through them}$
