A meteorologist records the temperature is at  $-7.5\degree C$  at 7 a.m. and as  $-4.3\degree C$  at 10 p.m. Which statement is true?

•  $-7.5\degree C\$  is colder than  $-4.3\degree C$ , which can be expressed by the inequality  $-7.5\degree C<-4.3\degree C$  

•  $-7.5\degree C\$  is colder than  $-4.3\degree C$ , which can be expressed by the inequality  $-7.5\degree C>-4.3\degree C$  

•  $-7.5\degree C\$  is warmer than  $-4.3\degree C$ , which can be expressed by the inequality  $-7.5\degree C>-4.3\degree C$  

•  $-7.5\degree C\$  is warmer than  $-4.3\degree C$ , which can be expressed by the inequality  $-7.5\degree C\degree<-4.3\degree C$  

Which statement about -8 and -12 is true?

• The value of -8 > -12 because -8 is located above -12 on a vertical number line.

• The value of -8 > -12 because -8 is located below -12 on a vertical number line.

• The value of -8 < -12 because -8 is located above -12 on a vertical number line.

• The value of -8 < -12 because -8 is located below -12 on a vertical number line.
