Part 2: On your own paper, graph this equation using the intercepts method. In the space provided, explain, in words, each step of the procedure you used. Make sure to use complete sentences and correct grammar. (3 points)

@AriPotta ;* Sorry for bein' such a pain in da bum, but I need some help wife.

Answer 1

solve for y first, isolate it

Answer 2

for part 1 ,

you want it to look like y=mx +b

Answer 3

Ok. One sec.

Answer 4

So it would be: y = 2x + 14, right?

Answer 5

NO

Answer 6

not exactly. 3y=-7x + 42
What is the next step

Answer 7

(This is why I need Harry/Ari)
Oh holy christ, I didn't see the negative sign sorry.

Answer 8

It would be y= -2x + 14 right?
Have a feeling that's still wrong o.o Math & I don't get along.

Answer 9

sorry, i didn't notice the notification! </3

Answer 10

think of it like this if I had 5+2 = 7 and I told you to find the 2 by itself you would move the 5 over by subtracting, right? so 2=7-5

Answer 11

its the same thing except you have variables

Answer 12

Harry; you left me.
Zebo; mmk I think I see what you're saying.

Answer 13

i'm sorry! :c

Answer 14

We're over, clearly. Unless you can explain this too me? :*

Answer 15

ok so you've gotten this far:

3y = -7x + 42

but it's still not in slope-intercept form. you gotta divide both sides by 3. what do you get when you do that?

Answer 16

Eh, sorry. Computer is dreadfully slow tonight.
I got ; y = -2x + 14 but that isn't right, is it Harry?

Answer 17

no because -7/3 isn't -2

Answer 18

you're going to keep it -7/3

y = -7/3x + 14

Answer 19

Oh I see what you did there, Harry.

Answer 20

so when graphing, you plot the y intercept first. which is (0,14)

Answer 21

then you use the slope to plot the next point. slope is rise over run, so from the y-intercept, go down 7 and over to the right 3

Answer 22

Ya, I see what you're gettin' at Harry :3

Answer 23

plot that, then put a line through le points

Answer 24

and you've just graphed teh line

Answer 25

*le'points.
Thanks Harry :3 Once again you've saved Hogwarts I mean my booty.

Answer 26

well that's because i love ur booty

Answer 27

oh we have to do the interepts method too

Answer 28

intercepts*

Answer 29

Well yes of course you love my booty, and Cols. *duuuh*
Oh yeah.

Answer 30

so this time, we gotta find the x- and y-intercepts. we'll use the standard form.

7x + 3y = 42

for x-intercept, substitute 0 for y

7x + 3(0) = 42
7x = 42
x = 6

x-intercept = (6,0)

for the y-intercept, substitute 0 for x

7(0) + 3y = 42
3y = 42
y = 14

y-intercept = (0,14)

Answer 31

now just plot those 2 points and put a line through em

Answer 32

Oh I see what you did there, Harry.
You're to smart for your own good, Potter.
This exam has taken me like 2 hours, because Tumblr started working again right as I sat down to do it. >.<

Answer 33

lol

Answer 34

how many questions left? or are you done?

Answer 35

After this one, like ... 2 I think.
So distracted by Eddie in a suit, Ari... I can't take it anymore.
Anyways, almost done - then we can draw faces on cats together. Yay!

Answer 36

yey! we still have the twiddla open so pop in once you're done, mmk

Answer 37

mmk, Harry I will.
