Question

4x-2y=-8

Answer 1

x=(-8-2y)/4
y=(-8-4x)/-2

Answer 2

was there a question along with
\[4x-2y=8\]? find the intercepts? graph? something?

Answer 3

4x-2y=-8 and its graphing.. and i must say where the y intercepts. my tutor is terrible

Answer 4

how did i guess

Answer 5

find the x intercept by replacing \(y\) by zero (mentally) and solve \[4x=8\] for \(x\) in one step

Answer 6

let me know when you get \(x=2\)

Answer 7

i dont know
i did 4(o)-2y=-8 but i dont know how to get to the next step and graph it and intercept the y

Answer 8

im so sorry i sound really stupid.

Answer 9

we can go slow, no worries

Answer 10

you are amazing

Answer 11

first off are we finding the x intercept or the y intercept
you pick

Answer 12

maybe this will make more sense?

Answer 13

ok it is asking for the y intercept so that is the one we will find

Answer 14

yay, so whats the first step?

Answer 15

replace \(x\) by zero in \[4x-2y=8\] and start with
\[-2y=8\]

Answer 16

divide by \(-2\) and get \(y=-4\) so the y intercept is \((0,-4)\)

Answer 17

oh because two negatives make a positive 8?

Answer 18

yes, and also because
\[\frac{8}{-2}=-4\]

Answer 19

how would i graph this?

Answer 20

let me look at the screen shot again

Answer 21

ok lets back up again

Answer 22

kk

Answer 23

the equation is not
\[4x-2y=8\] is is
\[4x-2y=-8\] so we have to change our answer

Answer 24

ok

Answer 25

y intercept
\[-2y=-8\\
y=4\]

Answer 26

it says "answer as an ordered pair" put in \((0,4)\)

Answer 27

ok got it

Answer 28

but how does one graph this phenomena

Answer 29

the x intercept, which you were not asked for , but you need to graph, is
\[4x=-8\\
x=-2\] so it is \((-2,0)\)
you have to make your line go through those two points
i will try to draw an example here

Answer 30

okay trying

Answer 31

not very phenomenal but i tried

Answer 32

paid someone 80 bucks to help me with this stuff and look where it got me :(

Answer 33

lol i charge $100
$200 if you want correct answers

Answer 34

in any case you got the picture more or less? should look somewhat like the one i drew

Answer 35

wow! but you are good though.. so it makes sense.. so the y intercept is (-2,0) right

Answer 36

oh no dear that is the \(\huge x\) intercept, where the line crosses the x axis

Answer 37

the y intercept was \((0,4)\)

Answer 38

hold the phone

Answer 39

you got the graph right, but y ou wrote \((-2,0)\) for the y intercept, that is wrong, it should be \((0,4)\)

Answer 40

so do i change the -2,0 to 0,4

Answer 41

yes please

Answer 42

wow thank u so much

Answer 43

yw
you got another or are you done?

Answer 44

ya i do
3x+4y=12 and i must find out where the y intercepts, type it in ordered pair as well as the x intercept

Answer 45

ok what first the x intercept or the y intercept
you pick

Answer 46

y
then x

Answer 47

ok for y put \(x=0\) and solve
\[4y=12\]

Answer 48

let me know when you get \(y=3\)

Answer 49

now lets keep careful track of the answers
the y intercept is \((0,3)\)

Answer 50

how about the x intercept?

Answer 51

ya i got it yay! yes now the x..wow thank you sweetie

Answer 52

the x intercept is what you get when you replace \(y\) by \(0\) and solve
\[3x=12\]

Answer 53

you should get
\[x=4\] making the x intercept \((4,0)\)

Answer 54

whoa, i got the same answer, i dont nkow why my tutor made this SO complicated

Answer 55

ok so now we know the x and y intercepts, lets graph them carefully

Answer 56

-x+4y=8

would i just put a -1 for x on the graph sheet?

Answer 57

i didnt have to graph the other one but i have to do this one

Answer 58

\[-x+4y=8 \] right?

Answer 59

no you do not put a minus one anywhere

Answer 60

we gotta do the same thing as before
find the x and y intercepts

Answer 61

put \(x=0\) get
\[4y=8\\
y=2\] so \((0,2)\) for the y intercept
