In order to graph this line, first let's find two ordered pairs that are solution to the equation.
To do so, let's choose two values of x and calculate the corresponding values of y.
Using x = 0 and x = 2, we have:
[tex]\begin{gathered} x=0\colon \\ y=3-0=3 \\ \\ x=2\colon \\ y=3-1=2 \end{gathered}[/tex]Now, graphing the points (0, 3), (2, 2) and the corresponding line, we have:
