# What are Inequalities?

##### 1 Answer

They are basically regular functions, but instead of equal signs, they use a variant of less than ">" or greater than "<" in place of the equal sign.

To keep things simple, refer to the function:

It is a basic line. Whatever you plug in a value x, it must fulfill a value for y. If x=1, y must equal 5.

Then you have inequalities.

Basically, every value for x and y above *or* on the line will work as an answer. The point (0, 4) is a good answer, because:

Because this is *or* on the line will work as an answer. (0, 0) works because:

Finally there are the non-equal inequalities:

Like the previous inequalities, greater than is anything above the line and less than is anything below the line. The main difference? Anything on the line is *not* an answer.

Referring to point (1,5)

Is false.

Once you remove the "or equal" part, the entire line is not an answer. On a graph, this line is usually dotted to mean that the line is not an answer, but just a boundary on what can be an answer.
