The scatter plot below shows data for the average cost of a high-end computer ( y , in dollars) in the year x years since 2000 . The least squares regression line is given by ˆ y = − 1677 + 314 x . A coordinate plane has a horizontal x-axis labeled Year from 4 to 12 in increments of 2 and a vertical y-axis labeled Cost in dollars from 0 to 2000 in increments of 500. The following points are plotted: left-parenthesis 6 comma 250 right-parenthesis, left-parenthesis 7 comma 550 right-parenthesis, left-parenthesis 9 comma 1000 right-parenthesis, left-parenthesis 10 comma 1300 right-parenthesis, and left-parenthesis 11 comma 2000 right-parenthesis. A line rises from left to right, passing through left-parenthesis 7 comma 550 right-parenthesis and left-parenthesis 10 comma 1500 right-parenthesis. All coordinate are approximate. Interpret the y -intercept of the least squares regression line. Select the correct answer below: The predicted cost of a computer in the year 0 is − $ 1677 . The predicted cost of a computer in the year 2000 is $ 314 . The predicted cost of a computer in the year 2000 is $ 1677 . The y -intercept should not be interpreted.
