Rewrite 2x + 3y = 9 in slope-intercept form and then graph the line.

OpenStudy (anonymous):

y=(-2/3)x+3

OpenStudy (anonymous):

oh thank you but i have more :)

OpenStudy (anonymous):

this is the graph http://s10.postimg.org/65pij8789/eeee.png

OpenStudy (anonymous):

C'mon @andieboo1995 ask

OpenStudy (anonymous):

oh okay

OpenStudy (anonymous):

Find the x and y intercepts of the following line and then graph the line: 3x + 4y = 12

OpenStudy (anonymous):

for x=0 y=3, for y=0 x=4

OpenStudy (anonymous):

so theres no line to graph right

OpenStudy (anonymous):

i'll draw it

OpenStudy (anonymous):

oh okay :)

OpenStudy (anonymous):

:) you can u help me with more plz

OpenStudy (anonymous):

if i can why not

OpenStudy (anonymous):

Write the equation of a line that goes through the points (0, 2) and (-3, 2). ok thank u i really appreciate it

OpenStudy (anonymous):

y=2 is the equation

OpenStudy (anonymous):

really

OpenStudy (anonymous):

not sure

OpenStudy (anonymous):

what about this one Write the equation of a line that goes through the points (3, -4) and (3, -2). Write the equation of a line that goes through the points (1, 4) and (2, 2).

OpenStudy (anonymous):

these ones sorry *

OpenStudy (anonymous):

its okay ill try to work it out ;)

OpenStudy (anonymous):

@andieboo1995 i'm doing the first

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

(1, 4) and (2, 2) y=2x-2 ,the first equation is a little bit hard

OpenStudy (anonymous):

yeah ikw;/ im trying to work it out

OpenStudy (anonymous):

@andieboo1995 for the (3, -4) and (3, -2) to calculate m we'll get 2/0 ,Since the denominator is zero, the slope is undefined can only say that the equation is a vertical line through x=3, then the equation is x=3

OpenStudy (anonymous):

Yeah i was trying to figure that out

OpenStudy (anonymous):

that's the correct answer

OpenStudy (anonymous):

thank you:)

OpenStudy (anonymous):

@andieboo1995 this is the graph if you want to understand more http://s12.postimg.org/xame9qc31/eeee.png

OpenStudy (anonymous):

awwww thanks :)

OpenStudy (anonymous):

@andieboo1995 about the (1, 4) and (2, 2) we made a mistake y=-2x+6

OpenStudy (anonymous):

oh really lol

OpenStudy (anonymous):

need a help?

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

ok i'm in

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

hurry I'm waiting

OpenStudy (anonymous):

/Users/macuser/Desktop/m2_05_q1.gif

OpenStudy (anonymous):

sorry hold on

OpenStudy (anonymous):

6x^3-16x^2 +17x-6)divided(3x-2)

OpenStudy (anonymous):

6x^3-16x^2+17x-6=(2x^2 -4x+3)(3x-2) then the result is (2x^2 -4x+3)

OpenStudy (anonymous):

|dw:1374761489491:dw|

OpenStudy (anonymous):

LOL COOL I HAVE MORE :)

OpenStudy (anonymous):

ok but last one i'm living in gmt zone it's 3:20 pm and i didn't sleep last night ok sister

OpenStudy (anonymous):

oh okay :(

OpenStudy (anonymous):

(3x^3+17x^2+15x2)divided (x+5)

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

@andieboo1995 vrify the equation i think there's a mistake 3x^3+17x^2+15x2

OpenStudy (anonymous):

no its correct i double checked

OpenStudy (anonymous):

15x2?? is it 30 or 15x^2

OpenStudy (anonymous):

its 15^2

OpenStudy (anonymous):

noo its 15+2x sorry

OpenStudy (anonymous):

15x2

OpenStudy (anonymous):

rewrite all of it please

OpenStudy (anonymous):

okay 3\[(3x ^{3}+17x ^{2}+15x+2)\div(x+5)\]

OpenStudy (anonymous):

better:)

OpenStudy (anonymous):

wait did u rewrite it

OpenStudy (anonymous):

while i was drawing i made some mistakes

OpenStudy (anonymous):

oh okay

OpenStudy (anonymous):

let's restart

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

the solution is (3x^2 +2x+5) -23/(x+5)
