Question

Continuing the previous problem, use the data points (1950, 0.75) and (1997, 5.15) to find the slope. Show all work necessary for your calculations. If necessary, round your answer to the hundredths place. What does the slope represent in the context of the problem?

Answer 1

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)`

`=(4.4)/(47)`

`=0.0936170212766`

`\approx 0.094`

Also, Slope represents the average rate of change.
