The graph AB shown in figure is a plot of temperature of a body in degree celsius and degree Fahrenheit. Then

A

(a)Slope of line `AB` is `9//5`

B

(b)Slope of line `AB` is `5//9`

C

(c)Slope of line `AB` is `1//9`

D

(d)Slope of line `AB` is `3//9`

Text Solution

Verified by Experts

The correct Answer is:
B
Slope of line `AB`
= `(DeltaC)/(DeltaF) = (100-0)/(212-32)-(100)/(180) = (5)/(9)`
