The inequality is represented by a solid line, if
1. The sign of inequality is
[tex]\leq[/tex]2. If the sign of inequality is
[tex]\ge[/tex]That means the sign of inequality must have = with it
Then the answers should be
[tex]\begin{gathered} -2y+x\leq-10 \\ x\ge4 \end{gathered}[/tex]Both are represented by a solid line
