Based upon data from his AP United States History class, Mr. Unsworth determined that the relationship between a student's hours watching TV per week (x) and that student's score on the AP (y) exam were
negatively correlated. He determined that the equation of the best fit line is y = -0.212 + 5.22. Based upon
these results, predict a student's AP score (to the nearest whole number) if he watches 12 hours of TV a week.

Need this asap if anyone can i would be very grateful. if you could show workings that would really
