PLEASE HELP I REALLY NEED IT!!!!!!

OpenStudy (anonymous):

Part A: Nadia rented a stage platform at $410 for 4 days. If she rents the same stage platform for 8 days, she has to pay a total rent of $770. Write an equation in the standard form to represent the total rent (y) that Nadia has to pay for renting the stage platform 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)

@SolomonZelman @bohotness @poopsiedoodle @TheSmartOne

OpenStudy (xapproachesinfinity):

your equation would be of the kind y=mx+b where y represents the total rental payment and x is how many days rented

OpenStudy (xapproachesinfinity):

do you know how to find the slope

OpenStudy (xapproachesinfinity):

you are given two points (770, 8) and (410, 4)

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

@xapproachesinfinity

OpenStudy (xapproachesinfinity):

well what is the slope?

OpenStudy (xapproachesinfinity):

how do you find the slope

OpenStudy (anonymous):

y=mx +b ?

OpenStudy (anonymous):

or y1-x1/y-x2?

OpenStudy (xapproachesinfinity):

that is the equation not the slope the slopl=e is just m

OpenStudy (anonymous):

oh srry

OpenStudy (xapproachesinfinity):

it is \[m=\frac{y_2-y_1}{x_2-x_1}\]

OpenStudy (anonymous):

ok

OpenStudy (xapproachesinfinity):

now i have given you the points you need above

OpenStudy (anonymous):

so what is the equation ?

OpenStudy (xapproachesinfinity):

first find the slope before finding the equation

OpenStudy (xapproachesinfinity):

use the point i wrote above you have y_2, y_1 x_2, x_1

OpenStudy (xapproachesinfinity):

these are the two points \[(770, 8)\] and \[(410, 4)\]

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

4-8/410-770 @xapproachesinfinity

OpenStudy (xapproachesinfinity):

the opposite my friend

OpenStudy (anonymous):

? please show me

OpenStudy (xapproachesinfinity):

eh my mistake i wrote it inccorectly

OpenStudy (xapproachesinfinity):

should be \[(8, 770)\] and \[(4,410)\]

OpenStudy (anonymous):

770-410/8-4?

OpenStudy (xapproachesinfinity):

so it should be 770-410/8-4

OpenStudy (xapproachesinfinity):

yes

OpenStudy (anonymous):

slope is 90

OpenStudy (anonymous):

m= 90 right ?

OpenStudy (xapproachesinfinity):

yes

OpenStudy (xapproachesinfinity):

now you have y=90x+b to find b just plug in (4, 410) so 410=90(4)+b then solve for b

OpenStudy (anonymous):

b=-50?

OpenStudy (anonymous):

or positive?

OpenStudy (anonymous):

@xapproachesinfinity

@Nnesha @confluxepic @pooja195

pooja195 (pooja195):

There are not negatives so positive also WELCOME TO OPENSTUDY!! :D

OpenStudy (anonymous):

@sleepyjess

OpenStudy (xapproachesinfinity):

well 410 is bigger than 360 so why did you get a negative you should have b=50
