Explanation:

Step1: Isolate x

Divide both sides of the inequality $2x\geq - 4$ by 2. Since 2 is positive, the direction of the inequality sign remains the same. So we have $\frac{2x}{2}\geq\frac{-4}{2}$.

Step2: Simplify

$x\geq - 2$.

Answer:

Inequality Notation: $x\geq - 2$
To graph on the number - line: Place a closed circle at - 2 (because the inequality is $\geq$) and draw a line to the right of - 2.
