Part a: maria rented a coat at $285 for 3 days. if she rents the same coat for 6 days, she has to pay a total rent of $510.

write an equation in the standard form to represent the total rent (y) that maria has to pay for renting the coat 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)

(3,285)(6,510)
slope = (510 - 285) / (6 - 3) = 225/3 = 75

y = mx + b
slope(m) = 75
use either of ur points...(3,285)...x = 3 and y = 285
now we sub and find b, the y int
285 = 75(3) + b
285 = 225 + b
285 - 225 = b
60 = b

equation is : y = 75x + 60...but we need it in standard form..

y = 75x + 60
-75x + y = 60
75x - y = -60 <== standard form

function notation is : f(x) = 75x + 60

x axis labeled days, and y axis labeled total costnot to sure of the intervals...sorry.
y = 75x + 60slope = 75...y int = (0,60)x int = (- 4/5,0)
