(GIVE A MEDAL AND FAN) PLEASE HELP!!!
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)

@EmilyF03 do u know what standard form is

- anonymous

no :/

- anonymous

are you there? @DaBest21

- anonymous

ok standard form is A*x+B*y=C

- anonymous

okayy so whats nexts?

- anonymous

is this flvs

- anonymous

yes :(

- anonymous

what lesson

k one sec

- anonymous

ok

B)f(x)=75x+60
C) To graph you would start at (0,60) and go up with a slope of 75 use intervals of 1 on the x axis and intervals of 75 on the y axis.

ill do a real quick one sec

OKAY

Let (3,285) and (6,510) reprsent the coordinate points, where x = number of days coat is rented for; and y = price of rental
Given these 2 points, we could write the equation of the straight line.
We need the slope.
Slope = (510-285)/(6-3) = 225/3 = 75
So the slope is 75.
So the equation of the line is y - 285 = 75(x - 3)
y - 285 = 75x - 225
y = 75x + 60

THAT its for part B? right? @mathway

- anonymous

the above isnt standard form

- anonymous

@mathway it says standard form no variables can be on the right

- anonymous

−75x+y=60 is a correct standard form equation

- anonymous

and @mathway plz do not copy and paste answers from previous questions about this

- anonymous

its in the code of conduct

- anonymous

@DaBest21 so the correct answer for part B its: −75x+y=60

- anonymous

yes

- anonymous

@DaBest21 It is best to guide them first before giving the answers! and for your quetsion, I lost the connection, so I wasn't able to type it next to my last comment. :/

- anonymous

Remember that the standard form is ax+by=c

- anonymous

i know

- anonymous

and for part C the correct answer its: To graph you would start at (0,60) and go up with a slope of 75 use intervals of 1 on the x axis and intervals of 75 on the y axis. ???

- anonymous

1y=y

- anonymous

yes

- anonymous

oops forgot the to put the link. again due to the lost of connection. Are we clear now, NOT @DaBest21 ?

- anonymous

whoa calm down ok

- anonymous

potassium.

- anonymous

and for part A? @DaBest21

- anonymous

-75x+y=60 but if u want to be thechnical do -75x+1y=60 which changes nothing

- anonymous

i was directing the end of that not at u @EmilyF03

- anonymous

Part A: -75x + 1y = 60,
Part B: f(x)=75x+60
Part C: To graph you would start at (0,60) and go up with a slope of 75 use intervals of 1 on the x axis and intervals of 75 on the y axis.

- anonymous

??/

- anonymous

yes

thank you!!!! @DaBest21 and @mathway
