Prompt

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?

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

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

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

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