Hi, from the question given that here there exist a linear relationship between degree celsius and the degree fahrenheit.
00:09
So, it can be represented as c is equal to a plus bf.
00:16
So, c represents the degree celsius and f represents the degree fahrenheit.
00:20
And also by the given condition 32 degree celsius sorry 32 degree fahrenheit equal to 0 degree celsius.
00:30
And similarly 212 degree fahrenheit is equal to 100 degree celsius.
00:37
So, by using this we need to find the value of a and b.
00:41
So, substituting the values in the above expression.
00:45
So, we obtain a plus 32 b is equal to 0.
00:51
Similarly a plus 100 and sorry 212 b is equal to 100 degree celsius.
01:01
So, solving this so we obtain when we subtract we obtain.
01:13
So, minus 180 b is equal to minus 100...
