Question

Part A: Eveline rented a car at $180 for 4 days. If she rents the same car for 9 days, she has to pay a total rent of $325.

Write an equation in the standard form to represent the total rent (y) that Eveline has to pay for renting the car for x days. (4 points)

Part B: Write the equation obtained in Part A using function notation. (2 points)

Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals. (4 points)

Answer 1

i got 30 minutes

Answer 2

Part A
(4,180)
(9,325)
slope =\[\frac{ y2-y1 }{ x2-x1 }\]
slope =
\[\frac{ 325-180}{9-4 }\]
slope =29
y=mx+c where m is the slope
Using one of the point
325=29(9)+c
325=261+c
c=325-261
c=64
y=29x+64
Part B
f(x)=29x+64
Part C
To graph the above equation you just need to plot the points (4,180) and (9,325) and then draw a line joining the two points.
