Answer:

• Graph C

,

• (-∞, -2]

Step-by-step explanation:

Given the inequality:


-3x\ge6

Divide both sides of the inequality by -3.


\begin{gathered} -(3x)/(-3)\le(6)/(-3) \\ x\le-2 \end{gathered}

Note that when you divide by a negative number in inequality, the inequality sign is reversed.

• The correct graph of the solution set is Graph C. (This is because the closed bracket [ is used).

• The solution in interval notation is:


(-\infty,-2\rbrack
