Given: x+y≤3
[tex]\begin{gathered} x+y-x\leq3-x \\ y\leq3-x \end{gathered}[/tex]So, we have:
For x = 0,
[tex]\begin{gathered} y\leq3-0 \\ \begin{equation*} y\leq3 \end{equation*} \end{gathered}[/tex]For x = 3,
[tex]\begin{gathered} y\leq3-3 \\ y\leq0 \end{gathered}[/tex]And the coordinates are:
(0, 3) and (3,0)
Next, graphing:
