Step-by-step explanation:
To find the temperature decrease by 0.5 degrees every hour we will find the slopes of the lines given in every option.
Option (1) [Top left graph]
Slope = 
= 
= -10
Option (2) [Top right]
Slope = 
= -0.5
Option (3) [Bottom left]
Slope = 
= -1
Option (4) [Bottom right]
Slope = 
= -12
Therefore, Graph given in option (2) will represent the decrease in temperature by 0.5 degrees per hour.
