The scatterplot shows the relationship between two variables, $x$ and $y$, for data set P. A line of best fit for the data is also shown. Data set Q is created by adding 649 units to the value of $x$ for each data point from data set P. Which of the following could be an equation of a line of best fit for data set Q?

A

$y=19.49+\frac{1}{100}x$

B

$y=18+\frac{1}{100}x$

C

$y=9+\frac{1}{100}x$

D

$y=6.51+\frac{1}{100}x$
