In 1998, it was 68.2 years. Let E represent the life expectancy in year t and let t represent the number of years since 1993. --- You have 2 points: (0,65.8) and (5,68.2) --------------------------------------------- Below is the queation. The linear function E(t) that fits the data is?: slope = (68.2-65.8)/(5-0) = 2.4/5 = 0.48 --- t-intercept = f(0) = 65.8 -------------------------------- Equation: E(t) = 0.48t+65.8 ==================================== Cheers, Stan H. E(t)= ? t+ ?
