See a solution process below:

Explanation:

To solve, subtract #color(red)(2)# from each side of the inequality to solve for #b# while keeping the inequality balanced:

#b + 2 - color(red)(2) >= 4 - color(red)(2)#

#b + 0 >= 2#

#b >= 2#

To graph, draw a vertical line at #2# on the horizontal access and shade to the right. The vertical line will be solid because the inequality operator contains a "or equal to" clause. We will shade to the right of the line because the inequality operator contains a "greater than" clause:

graph{x-2>=0}
