Integers are whole numbers that go from negative infinity to positive infinity. As such, they do cover the negative range of the number line.
Irrational numbers can be graphed at a number line, but only as an estimation.
well the rate of change is how much something changes in a matter of time, so it can be graphed in a slope because slopes can represent changes ( negative and positive, zero and undefined)

When you divide or multiply two negative numbers they cancel each other out and you have a positive answer. We are measuring relationships instead of moving on a number line like addition or subtraction.
