Lets assume
T = 195;
T = 0; when x = 2;
T = 195; when x = 4;
What is the relation between T and x?

Would a line work here? – JG123 Nov 24 '19 at 17:51

such as $T=195(x-2)/2$? – J. W. Tanner Nov 24 '19 at 17:52

@J.W.Tanner thanks for the answer, its working as expected – Subhajit Das Nov 24 '19 at 18:30

You wrote $'{T=195}'$ and '$T=195$ when $x=4$'. Was the first a mistake? – J. W. Tanner Nov 24 '19 at 18:36

$T(x)=195(x-2)/2$ is a linear function with $T(2)=0$ and $T(4)=195$.
There is a linear relationship between two points.
I found it by eyeballing, but if you wanted to be pedantic you would solve
$T(x)=ax+b, T(2)=2a+b=0,$ and $T(4)=4a+b=195.$
You would get $(4a+b)-(2a+b)=2a=195$ and $b=-2a=-195$.
