Answer:

PART A:

Recall that the equation of a line in standard form is of the form:

ax + by = c

where a, b, and c are constants.


The equation of a line passing through two points:

and

is given by:



Given that Amir rented a scooter at $43 for 3 hours. If he rents the same scooter for 8 hours, he has to pay a total rent of $113.


Thus,

and


Thus, the equation of the line is given by:



Therefore, the equation of the line in standard form is




PART B:

To write the equation with a function notation, we first express y in terms of x and then change y notation to f(x) notation.


Recall from part 1:



Therefore, the equation obtained in Part A written using function notation is given by:




PART C:

To graph the equation obtained above, we draw the x- and y- axis with the x-axis labelled 'number of hours' and the y-axis labelled 'total rent'.


Next, we choose appropriate scales for x- and y- axis. Depending on the size of your graph book, you can choose an interval of 1 unit for the x-axis and an interval of 10 units for the y-axis.


From part A, we know that the line of the equation passes though points (3, 43) and (8, 113), mark these points and draw a straight line passing theough these points.
