i have an equation 0.02q=T1-T2

how do i plot a graph between T2 and T1......since all the three are variables i am not able to plot the graph between T2 and T1.....kindly help....is der any method to approximate variable q to a constant? so dat i can plot the graph

If you think of (T1 - T2) as a single variable (delta temperature), you have an equation of a line and could plot q as the dependent variable vs (T1 - T2) as the dependent variable.

taking t1-t2 as difference of T we could sure plot a graph between diff(T) Vs q......but i need a plot btw T1 and T2....

If you want plot T2 as a function of T1, there are a couple of options. One is a 3D plot where the independent variables are T1 and q. In this case the plot will be a planar surface. Another option is in a 2D plot consisting of a series of parallel lines with each line corresponding to a different value of q.
