no

So, you have to draw the graph?
Here is what it should look like:|dw:1378015117111:dw|

- anonymous

I've added a few numbers just to show you the scale.

- anonymous

The first ordered pair is (-4,8)
That means to start at the origin and count -4 along the x-axis, then +8 along the y-axis.

- anonymous

|dw:1378015296065:dw|
(-4,8) is where the two line intersect.

- anonymous

okay

- anonymous

Do the same for the rest of the points and they should form a straight line.

- anonymous

I suggest you get some graph paper, it will make your life a lot easier.... There are notebooks of graph paper or loose leaf graph paper.

- anonymous

i am trying to see how it will make a line

- anonymous

can you show me another point and maybe i will understand that one

- anonymous

|dw:1378016201262:dw|

- anonymous

okay i still dont see a line

- anonymous

Graph the rest of the points first.

- anonymous

thank you

- anonymous

Do you see the line?

- anonymous

no

- anonymous

Plot some of the points on the graph that I drew.

- anonymous

|dw:1378016479304:dw|

- anonymous

is this right

- anonymous

Yes, it is. Keep plotting points.

- anonymous

so the line is straight

- anonymous

Yes it is.

- anonymous

okay

- anonymous

|dw:1378017047971:dw|

- anonymous

First you should find the pair ....
Do it ...
Lets answer together !

- anonymous

i think my line is wrong

- anonymous

Find (-4 , 8)=A
(-2 , 4 )=B
In the system !

- anonymous

i thought we did that already

- anonymous

Draw a system first !
Please ...:)

- anonymous

okay i am new to this so i am having trouble understanding

- anonymous

please help do you mean drawn a line

- anonymous

is that the system

- anonymous

Ok !
Dont need !
always we should have : Y = mX+d
First find m :
You know m=X/y
Ok ?!
When you want to find m you shold have two diffrent pair and fhnd them .
Then you should be do this :
pair1/pair2=m
Ok?!
Now we have m .
Understand this first ?:D

- anonymous

yes

- anonymous

OK !
Very good !
so now we have two different pair in problem !
They re A = (-4,8)&B=(-2,4)
OK?!

- anonymous

okay

- anonymous

And now find m :?

- anonymous

okay

- anonymous

i don't understand what this has to do with drawing a line graph

- anonymous

i just have to draw a line graph

- anonymous

Amm !
It s so easyer !
Find the pairs !

- anonymous

oh okay

- anonymous

so what do we do next

- anonymous

You found them in the last !
Now see this picture :

- anonymous

what picture

- anonymous

|dw:1062356470909:dw|

- anonymous

okay

- anonymous

Exacly its very interesting !
Now take a line from them !
See :

- anonymous

|dw:1062356653284:dw|

- anonymous

oh i see it finally

- anonymous

i was told the line was straight

- anonymous

It s straight !

- anonymous

|dw:1378019785878:dw|

- anonymous

this is straight

- anonymous

Yes .
In the math Look :

- anonymous

- anonymous

|dw:1062357380079:dw|
