ANSWER and EXPLANATION
A) To organize the measurements in ordered pairs implies that we want to put them in the form:
Therefore, the measurements in ordered pairs are:
Note: 4825 and 6000 are in millions (10⁶) of metric tons
B) To find the slope, apply the formula:
Therefore, the slope is:
C) To find the in point-slope form, we apply the formula:
Therefore, we have:
Note: the unit is in million metric tons
D) To show the equation in point-slope form, we have to put it in the form:
To do that, simplify the point-slope form of the equation:
E) To predict the emissions for the year 2020, substitute 2020 for x in the equation above:
That is the prediction for the year 2020.
