The given scatter plot shows x = age versus y test score data on a test: a) Determine the equation of the approximate line of best fit drawn on the graph. Use (20, 220) and (35, 280) for the coordinates of the points marked on the line with a +: line b) What do the slope and the y-intercept of your indicate? c) Use your equation to predict the test score for a 24 year- old test taker. d) Use your equation to predict the age of someone scoring 260 points on the test.
