Assume I have a table. The values inside the table are determined by y and x var

Question

Assume I have a table. The values inside the table are determined by y and x variables. But in this case it is t and p (or temperature and pressure). Those values for t and p don't correlate to my array in code ( for example on column = 0 the temperature= -120). That's what a and b are for. I want to be able to input a value between two rows or columns and use a y=mx+b equation to find it.I'm trying to make a linear interpolation from an array code. Yet if I plug in a value in between two coordinates it doesn't solve what is in between. If I give a t=-81.5 for example which is in between -80 and -85, it gives the value corresponding to t=-85. I want to be able to plug i say p=11 and t=-82.4 and get back a value that uses y=mx+b to give back a value from linear interpolation from the values around it. Can someone help me??

Result:

Input the temparture:81.5

Input the pressure:200

p1= 0 p2= 1.45e+27t1= 0 t2=62791.7The slop is: 4.3305e-23

the y interceptis: 0

the line equation is: y=(4.3305e-23)*x + 0

The answer is : 10.949
