Answer

Explanation:

Step1: Identify data points

For 1960 ($x = 0$), life - expectancy $y=66.8$; for 1970 ($x = 10$), $y = 67.3$; for 1980 ($x = 20$), $y=69.7$; for 1990 ($x = 30$), $y = 71.7$; for 2000 ($x = 40$), $y=74.4$; for 2010 ($x = 50$), $y=76.1$.

Step2: Analyze scatter - plot for part a

We plot the points $(0,66.8),(10,67.3),(20,69.7),(30,71.7),(40,74.4),(50,76.1)$ in the rectangular coordinate system. The correct scatter - plot will have these points in the correct relative positions.

Step3: Analyze line - drawing for part b

The points for 1980 ($x = 20,y = 69.7$) and 2000 ($x = 40,y = 74.4$) are used to draw a line. We find the line that passes through these two points among the given options.

Answer:

a. Without seeing the actual graphs, we cannot determine the exact answer. But you should look for a graph with points at $(0,66.8),(10,67.3),(20,69.7),(30,71.7),(40,74.4),(50,76.1)$. b. Without seeing the actual graphs, we cannot determine the exact answer. But you should look for a graph with a line passing through the points $(20,69.7)$ and $(40,74.4)$.
