I dont really know how to explain it but we need to work backwards....So to get from $\large{-2}$ to $\large{-4}$ we can add but to find out what we add by we need to subtract these two numbers....

$\Huge{-4 - (-2)=?}$

anonymous · Answer

@Wendy.Ivette11714 can you please help explain this?

wendy.ivette11714 · Answer

@KendrickLamar2014 can you help her?

563blackghost · Answer

I dont know if I went with the right approach @KendrickLamar2014

wendy.ivette11714 · Answer

Well den

kendricklamar2014 · Answer

Hmm I believe you did. -4 - -2 = ? What would that solve for @563blackghost

wendy.ivette11714 · Answer

I thought you can have 2 negative signs?

@563blackghost

563blackghost · Answer

When subtracting with a negative the negative turns to a positive....

$\Huge{-4+2=?}$

wendy.ivette11714 · Answer

That's correct

wendy.ivette11714 · Answer

So what is your answer @rainbowswirl

anonymous · Answer

-2 @Wendy.Ivette11714

wendy.ivette11714 · Answer

That is correct @rainbowswirl

anonymous · Answer

Is that all to it? @Wendy.Ivette11714

563blackghost · Answer

Now we have to apply -2 to the second two know points to see if it is the right rule....

$\Huge{1+(-2)=?=-1}$ Does it equal -1?

anonymous · Answer

Yes @563blackghost

wendy.ivette11714 · Answer

What he said

563blackghost · Answer

So that is our rule where we add -2 to x....

$\Huge{x+(-2)=y}$ Now we can use this rule to solve the rest of the table ^^

she* :P

anonymous · Answer

So -2 + ( -2 ) = y? @563blackghost

563blackghost · Answer

Well x is the input in the table so if we used -2 as x we would get -4 which is the second coordinates in the table....

563blackghost · Answer

So to solve the rest of the table we use the rule...

$\Huge{-3 +(-2) = ?}$

$\Huge{-1 +(-2)=?}$

$\Huge{0+(-2)=?}$

anonymous · Answer

-1, -1, wouldn't the -2 stay the same? @563blackghost

563blackghost · Answer

For the 3rd coordinate it would stay as -2 but the others are incorrect....

anonymous · Answer

I knew I messed up. Let me try again. @563blackghost

563blackghost · Answer

Alrighty

anonymous · Answer

-5 and -3 @563blackghost

563blackghost · Answer

Correct ^^ so the missing coords are -5, -3 and -2 as well as the rule being x=(-2)=y

563blackghost · Answer

x+(-2)=y*
