given data points:
2, 8
3, 7.25
---
to solve the linear equation, copy and paste this (the two given points):
2, 8, 3, 7.25
into the "Two-Point form: x1 y1 x2 y2" input box here: https://sooeet.com/math/linear-equation-solver.php

x-intercept = (12.6666667, 0)
y-intercept = (0, 9.5)
slope = -0.75
---
answer:
the linear model:
s(t) = -0.75t + 9.5
where:
t = minutes
s = length of candle (inches)
