# How do you graph x-1=y using the intercepts?

$\text{see explanation}$

#### Explanation:

$\text{find the intercepts as follows}$

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

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

$x = 0 \to 0 - 1 = y \Rightarrow y = - 1 \leftarrow \textcolor{red}{\text{ y-intercept}}$

$y = 0 \to x - 1 = 0 \Rightarrow x = 1 \leftarrow \textcolor{red}{\text{ x-intercept}}$

$\text{plot } \left(0 , - 1\right) , \left(1 , 0\right)$

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