To solve the inequality − 4x ≥ − 12, we need to divide both sides of the inequality by -4. However, whenever we divide by a negative number, the inequality sign flips.
Dividing both sides by -4, we get:
x ≤ 3
Therefore, the solution to the inequality is x ≤ 3.
To graph this inequality on a number line, we plot a closed circle at 3 and shade all the values to the left of 3.
The correct answer is a. x ≤ 3.
