Answer
$V = 4.5t + 147$
Work Step by Step
We will plug the known values into slope intercept form.
$m=4.5$
The value at year t=2 is 156 dollars
so the the value at the y intercept will be $156 -2m$
156 - 2(4.5)= 147
The V (value) intercept is 147
Plug in known information to slope intercept form.
The equation of the line is $V = 4.5t + 147$
