Answer 1

In the first graph, just state what the x and y values are for each point.
So, for point A x=-3 and y=2

Answer 2

What about the rest of them?

Answer 3

Well there are 3 graphs and the first one requires 6 answers. (I gave you one).
Maybe someone else might help you.

Answer 4

You gave me less than half of one, could you maybe help me with a simpler question of the three?

Answer 5

Basically, the people ask one question here and not just a whole bunch of them. Also, when people ask a question, they have done at least some amount of work on the problem. For example, for the 1st problem, what did you get for B?

Answer 6

I did do work on this, there are 5 other questions I didn't include because I did them. I just need to know what to do for these questions, I have tried all day and cannot do them at all.

Answer 7

That first graph is just a matter of seeing where the points lie on the graph. Do you want to try B?

Answer 8

Yes and C through F, if I could get your help on at least one question I can move along and ask the other two somewhere else.

Answer 9

Okay, what do you get as an answer to B?

Answer 10

x=4 y=-3 which sounds extremely wrong

Answer 11

X does equal 4 but y doesn't = -3
You see that point B lies along the x axis at point 4? that's x.
Now look at where point B is in relation to the y axis.
Or how high is point B above the x axis?

Answer 12

y=1?

Answer 13

That's right!!
Just determine precisely where the point lies.

Answer 14

I feel pretty silly now, the graph pretty much has the answers laid out for me. So would C be x=2, y=0?

Answer 15

Yes that's right.

Answer 16

Thanks okay I got question 1 down then, would you still be interested in helping me with question 2?

Answer 17

Well, okay because I gave you a bit of trouble already.
But see you learned.
Okay on to question 2.

Answer 18

Thank you!

Answer 19

Okay I'm guessing you don't know about graphing a function correct?
ALso do you know anything about absolute value? (That what those 2 vertical bars are.)
It's basically asking for you to take a positive value of what is inside.
Example | -5| =5
|(3*2)*-1| = 6

Answer 20

I know nothing of graphing a function or absolute value, absolutely nothing.

Answer 21

Wait those nubers are wrong !!!
I'll delete those and try again.

Answer 22

Okay I deleted them

Answer 23

Okay we are graphing y=|x-2|

X Y
-5 7
-4 6
-3 5
-2 4
-1 3
0 2
1 1
2 0
3 1
4 2
5 3

Answer 24

y or f(x)= x-2

Answer 25

To see how those numbers are generated let's try x=-5
y=|x-2|
So if x = -5 then y would equal -5-2 which would be -7 but those vertical bars tell us make that positive so it becomes 7.

Answer 26

Wait I'm confused which questions do I delete, and which one are we on?

Answer 27

We are on question 7 and I already deleted my answers so don't worry about that.

Answer 28

Okay so how do I graph f(x)= x-2

Answer 29

To graph that you need a series of x and y points so it is much easier to think of the function as y = |x-2|
We can work out a few of the points.
You can look at my answers above.
What is y when x=-5?

Answer 30

3?

Answer 31

No - but we can work it out
y = |x-2|
y = |-5 -2|
y = |-7|
Finally the vertical bard tells us to make that postivie so
when x = -5 then y = 7

Answer 32

Frank are you doing okay with this?

Answer 33

No I'm sorry this is really confusing, I know it sounds bad I rather just know the answers. This is really hard for me

Answer 34

Well I'll tell you what You do have the answers with the numbers I posted above.
Now I'll graph it for you.
Graph is attached.

Answer 35

So I draw this exact thing on a graph for question 2?

Answer 36

Yes, that is what you do.
OR if you download something called OpenOffice it will do it for you. (That's what I used).
OpenOffice is VERY similar to Microsoft Office but one big difference - it is free!! (and well worth learning).

Answer 37

My graph doesn't look like that, how do I know where to place the line? The graph you posted y goes up to 7 on mine only 5

Answer 38

I don't know how you are graphing yours but just graph it from x = -4 to x = +4

Answer 39

Answer 40

And use these numbers

X Y
-4 6
-3 5
-2 4
-1 3
0 2
1 1
2 0
3 1
4 2

Answer 41

Are you graphing that by hand? It should look a lot like the one I attached a few minutes. If you really want to plot it, use the numbers I just posted.

Answer 42

Remember to plot X and Y correctly.

Answer 43

By paint, my assignment is only for adobe so I can't graph anything. What are the exact x and y coordinates for me to draw

Answer 44

Here are the numbers. You might want to eliminate the first set because it has Y=6.
X Y
-4 6
-3 5
-2 4
-1 3
0 2
1 1
2 0
3 1
4 2

Remeber to plot these in EXACTLY the same positiions as I did on my graph.

Answer 45

I located a blank graph.
Perhaps you could use something like this?

Answer 46

Here's something more like what you need. It is a graph about 5 by 5.
(It runs from X -5 to X +5 and
Y -5 to Y+5)

Answer 47

Answer 48

That look much better. MAybe you could use a ruler and make it look a lot sharper. (that's up to you.)
As I also said you might want to use this graph to draw on.

Answer 49

Yes thank you I will try and do this later offline by hand for a straighter line. Thank you for your help, I'm going to ask my third question now elsewhere you've done more than enough for me thank you :)

Answer 50

Well I'm working on question 3 right now
If nothing else have someone look at it to see if I did it right.

Answer 51

Here's what I have for numbers.
Remember I did this very fast so have someone else look it over.
X Y
-7 17
-6 15
-5 13
-4 11
-3 9
-2 7
-1 5
0 3
1 1
2 -1
3 -3
4 -5
5 -7
6 -9
7 -11

Answer 52

Could you try drawing it on the graph I posted, it's really hard to figure out where the line should go when all the numbers are placed differently
