Question 15·Hard·Two-Variable Data: Models and Scatterplots

The scatterplot shows the relationship between $d$ and $t$ for data set P, where $d$ is the number of prototypes a team has already assembled and $t$ is the time (in hours) it takes to assemble the next prototype. A line of best fit is shown.

A new data set, P2, is created by transforming each point $(d,t)$ in data set P to a point $(U,V)$ using the rules

and

Which choice is the $V$-intercept of a line of best fit for data set P2?
