Question

Find the x- and y-intercepts of the graph of the equation: -2x - 2y = 0

Answer 1

Can you do this one?

Answer 2

I cant really do any of them. I'm new at this

Answer 3

If you want to find the x-intercept you susbstitute y by 0 and if you want to find the y-intercept you substitute the x by 0

Answer 4

this is all so confusing

Answer 5

Hmmm, what don't you understand from what I said above?

Answer 6

the whole graphing these point and all the susbstituting. I have an hr left and I'm going to fail this test

Answer 7

if you fail now you can always do better next time..

Answer 8

Not if I dont know what i'm doing
This class is the last class I need for my Bachelors

Answer 9

You'll not graph in this question. I'm trying to help you solve this question on your own.

Answer 10

i just have no idea what to do

Answer 11

It's easy. All you have to do is SUBSTITUTE this is the most easiest thing in math.

You have : -2x - 2y = 0

In order to find the x- intercept just put instead of y zero :

-2x-2(0)=0
-2x=0
x=0

(0,0)

You're going to do find the y-intercept. In order to find the y-interecpt put instead of x zero.

Answer 12

so the 2y will turn into 20?

Answer 13

no

Answer 14

you're going to multiply 2 by zero

Answer 15

because 2y = 2(0)

Answer 16

so 0?

Answer 17

Yes :)

Answer 18

So I would do that for x too?

Answer 19

but wait you want to find the y-intercept so you only susbstitute the x by zero not the y

Answer 20

=> -2x - 2y = 0
-2(0)-2y=0

now solve it..

Answer 21

Why is it saying x- and y-

Answer 22

whats the - for?

Answer 23

We already found the x-intercept you can't find them both at the same time

Answer 24

I don't know it's just a dash..

Answer 25

Don't worry about it

Answer 26

why cant i find them both at the same time?

Answer 27

so it would be answer D?

Answer 28

Because you won't get an answer! It would look like this :

-2x - 2y = 0
-2(0)-2(0)=0
0-0=0
0=0

Did you find x or y-intercept? No.

And yep :)

Answer 29

No and yep?

Answer 30

lol nevermind. Yes the answer is D

Answer 31

You still going to help? I have more

Answer 32

Sure!

Answer 33

D?

Answer 34

y = 5x

Answer 35

Yes

Answer 36

turn y to 0= 5(0) (0,0)

Answer 37

and x to 0?

Answer 38

Sorry, I didnt understand...

Answer 39

You mean that the answer is not D ?

Answer 40

I think it is D

Answer 41

Yes it is

Answer 42

That one was just like the last one

Answer 43

ok next one

Answer 44

Can you post the other one there

<----

Answer 45

I'm not sure how. its a file

Answer 46

how do I attach it to there

Answer 47

Don't worry about it just keep it here

Answer 48

k

Answer 49

x = 2

Answer 50

i have no idea on this one

Answer 51

I think its B

Answer 52

It's A

Answer 53

Oh shoot

Answer 54

I was thinking there was an x and y and it would be 0,0 again

Answer 55

No

Answer 56

What do you think?

Answer 57

So on this one. y is 0 = -2 so the answer would be B?

Answer 58

Exactly :)

Answer 59

yeaaaaaaaa

Answer 60

-6 - x =0

Answer 61

not sure how to do this one

Answer 62

-6 - x =0

solve for x

-x=6
x=-6

and remember x is a vertcal line

so the answer is...?

Answer 63

c

Answer 64

Yup :D

Answer 65

so why is x the veritcal line

Answer 66

always x is vertical and y is horizontal

Answer 67

on this attachment its showing that y is the vertical line

Answer 68

I realized that! I have no idea why though.

Answer 69

ok

Answer 70

I only have 10 min left on this test that i'm going to fail because I dont have enough time left for the remaining 15 questions. I can take it again for a better score. I have a total of 25 questions. Would it be too much to asked if you could help me through them?

Answer 71

Sure..

Answer 72

great. your a life saver

Answer 73

You're going take it again or you're going to continue?

ok great. can you let me know?

Answer 78

ok

Answer 79

thank you

Answer 80

I'm back.

Answer 81

ok

Answer 82

Determine which ordered pairs are solutions for y = 5x - 4
A. (0,-5) B. (0,-4) C. (2,-6) D. (4/5,0)

Answer 83

it wont let me copy and paste this time and i'm only getting an 1 45 min

Answer 84

Okay lets do this fast! I have to go in a a bit =(
