Answer:
Slope is 0.094,
It represents the average rate of change.
Explanation:
Since, the slope is the ratio of difference in y-coordinates and the difference in x-coordinates,
Also, in a order pair, first element shows the x-coordinate and second element shows the y-coordinate.
Here, the data points are (1950, 0.75) and (1997, 5.15),
Thus, the slope is,
![m=(5.15-0.75)/(1997-1950)](https://img.qammunity.org/2020/formulas/mathematics/college/kbi91sxac6okg400xsflqi7i8h6q7emxzq.png)
![=(4.4)/(47)](https://img.qammunity.org/2020/formulas/mathematics/college/d0dwesb2sp7uuhqttc7j2a1b7l6z23cs7s.png)
