Which statement about the temperatures -5.7°C and -5.9°C is true?

• -5.7°C > -5.9°C because -5.7°C is colder than -5.9°C.

• -5.7°C < -5.9°C because -5.7°C is warmer than -5.9°C.

• -5.7°C > -5.9°C because -5.7°C is warmer than -5.9°C.

• -5.7°C < -5.9°C because -5.7°C is colder than -5.9°C.

Which point shows the location of the number with the greatest absolute value?

• point A

• point B

• point C

• point D
