In order to graph this equation, let's calculate two points that are solutions to the equation.
To do so, let's choose two values of x and calculate the corresponding values of y:
[tex]\begin{gathered} x=0\colon \\ y=3-0=3 \\ \\ x=1\colon \\ y=3-4=-1 \end{gathered}[/tex]So we have the ordered pairs (0, 3) and (1, -1). Graphing these points and the line that passes through them, we have:
