Answer:

Option (2) [Graph on the top right]

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 =
$\frac{\text{Rise}}{\text{Run}}$

=
(-20)/(2)

= -10

Option (2) [Top right]

Slope =
(-2)/(4)

= -0.5

Option (3) [Bottom left]

Slope =
(-2)/(2)

= -1

Option (4) [Bottom right]

Slope =
(-60)/(5)

= -12

Therefore, Graph given in option (2) will represent the decrease in temperature by 0.5 degrees per hour.
