Answer
The line of best fit is :
y= 12.525 x+0.4
Work Step by Step
Let x be the ounces and y be the calories.
In Alegebraically form
Let :
( x_{1} ,y_{1}) ->(8100)
(x_{2},x_{2}) ->(20250)
Using the point-slope form :
$y-y_{1} = m(x-x_{1)}$
where: m= $\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}$
$\frac{250-100}{20-8}$
=$12.5$
By substituting
y-100=12.5(x-8)
By simplifying
y-100=12.5x-100
y=12.5 x
using graphingutility
The line of best fit is :
y= 12.525 x+0.4
