To see how the solution set changes, suppose the coordinate pair (a, b) satisfies the original inequality. if a stays the same, b must be its previous value to satisfy the new inequality.

No, If a stays the same b must be a value within the interval that satisfy the inequality.

Step-by-step explanation:

An inequality provides an interval as a solution. So, actually the solution of an inequality comprises many coordinate pairs. To show that, let's show this graphically. Instead of (a, b), let's work with numbers.

Let's use as an example a -b <0

1) Suppose a=1, b=3

2) If a stays the same value, i.e. 1, then b=?

Then b>1
