Recall that the inequality:
![xin interval notation is as follows:[tex](-\infty,a).](https://img.qammunity.org/2023/formulas/mathematics/college/be3znuet3i111ikbxltnkztgmhqjhzppx1.png)
And its representation on a number line is:
Therefore the given inequality in interval notation is:
![(-\infty,-6).](https://img.qammunity.org/2023/formulas/mathematics/college/ci4mofaulr2qcgvlidnriz58c8drjy5vez.png)
Its representation on a number line is:
