How do you solve and graph the solution of b+2>=4?

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}
