The correlation of SAT scores and grade point averages (GPAs) for a random sample of high school students is represented by the scatterplot below. 2400 2200 2000 1800 SAT Score 1600 1400 1200 1000 800 600 400 200 o 0 10 20 30 40 50 60 70 80 90 100 High School GPA The approximate line of best fit is given by the equation y = 40x - 1800. Based on this trend, which of the following best predicts the SAT score for a high school student with a GPA of 95? 2000 2200 Ο Ο Ο Ο 1980 1895
