The given numbers are

1

3.25

The opposite of 2. The opposite of a number has the same value with different sign, so in this case the number is -2.

-(-4). Here we multiply signs. So the number is 4.

Now, we must graph -2, 1, 3.25 and 4.

The image attached shows all four numbers drawn on a number line. The first number must be -2, because is the least, then number 1, then number 3.25 and at last number 4.
