Question

How do you solve and graph `b+2>=4`?

Answer 1

See a solution process below:

Explanation:

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 this we need to draw a vertical line at `2` on the horizontal axis.

The line will be a solid line because the inequality operator contains an "or equal to" clause which means the line will be part of the solution set.

We will shade to the right of the line because the inequality operator contains a " greater than" clause:

graph{x >= 2}
