Question

graph the inequality below on the number line. b≥ - 4

Explanation:

Step1: Identify the critical - point

The critical - point for the inequality $b\geq - 4$ is $b=-4$.

Step2: Determine the type of the point

Since the inequality is $\geq$, we use a closed - circle at $b = - 4$ on the number line.

Step3: Determine the direction of the graph

The inequality $b\geq - 4$ means $b$ can be equal to $-4$ or any number greater than $-4$. So, we draw a line to the right of $-4$ on the number line.

Answer:

On the number line, place a closed - circle at $-4$ and draw a line to the right of $-4$ towards positive infinity.
