Your answer is correct. Well done!
It is, for example, possible to show the number of houses built in Gauteng every year from 2000 to 2015 and the
number of ducklings born in Dublin in Scotland every year from 2000 to 2015. It is not clear why anyone would want
to do such a thing, but it is certainly possible!
The correct answer is 'False'.

Paul is a car salesman. The table below shows the salary that Paul earns for the number of cars sold in a month.
Please use the data to draw a graph on the set of axes below that shows the information and answer the question
below:
Which of the following statements is correct?
a. The slope of the line that represents the relationship between the number of cars sold and Paul's monthly
salary is 1/600.
b. The slope of the line that represents the relationship between the number of cars sold and Paul's monthly
salary cannot be calculated with the available information.
c. The slope of the line that represents the relationship between the number of cars sold and Paul's monthly
salary is -1/600.
d. The slope of the line that represents the relationship between the number of cars sold and Paul's
monthly salary is 600.
, e. The slope of the line that represents the relationship between the number of cars sold and Paul's monthly
salary is –600.
Your answer is correct.
The line will look as follows on the set of axes provided:
To explain how the slope of the line is calculated, we added points C and D. The slope can now be calculated as
follows:
When moving from point C to point D, Paul's salary increases from 4 600 to 5 200; it therefore increases by 600.
The change on the y-axis (the vertical axis) is therefore +600. When moving from point C to point D, the number of
cars sold increases from 1 to 2; it therefore increases by 1. The change on the x-axis (the horizontal axis) is
therefore +1. Now we can calculate the slope of the line as follows:
The correct answer is:
The slope of the line that represents the relationship between the number of cars sold and Paul's monthly salary is
600.
