Explain the error.

• -1.2 isn't an integer.

• -2 isn't a whole number and 3.4 isn't a rational number.

• -2 isn't a whole number and -1.2 isn't an integer.

• The numbers are graphed correctly.

Answer explanation

Explanation:

• -2 is an integer, but it is not a whole number because whole numbers are non-negative (0, 1, 2, 3, ...). So, -2 should not be placed in the "Whole Numbers" box.

• -1.2 is a decimal number, so it is not an integer. Integers include whole numbers and their negatives (without fractions or decimals). Therefore, -1.2 should not be placed in the "Integers" box.
