You have 2 points: (0,65.8) and (5,68.2)
---------------------------------------------
Below is the queation.
The linear function E(t) that fits the data is?:
slope = (68.2-65.8)/(5-0) = 2.4/5 = 0.48
---
t-intercept = f(0) = 65.8
--------------------------------
Equation:
E(t) = 0.48t+65.8
====================================

E(t)= ? t+ ?
