right. The inequality that is represented by each graph then describe the graph using interval notation and filling in the blanks for part. A couple of things to note before we get started is we're starting at the value of negative one on the number line, and we're going to the left, which means all numbers less than our starting value X is less than negative one. An interval notation. This is represented with the open parentheses, E a negative infinity and then a negative one and a closed parentheses. E for Part B. We're starting at two with a bracket, which means it includes that value, so X is greater than or equal to two. Going to the right is all numbers greater than so. We have the interval notation that starts with a bracket to include the number two, and it goes to the right all the way to positive infinity. And it closed parentheses. E
