Re: Area problems Please Help!!
That they would. y = x. Now plug in your original points.

Re: Area problems Please Help!!
You have ( 3, 3 ) AND ( -6 , -6 ), They are in the form ( x , y ). So ( x = 3 , y = 3 ) for the first. Now plug in to y = x, your equation. You get 3 = 3 , that's true!
- 6 = - 6 that's true! You are done the equation passes through the 2 points.

Re: Area problems Please Help!!
The way it is formatted it wants the answer to be X-Y = ___
What Would I put for the blank if the 3's cancelled out?

Re: Area problems Please Help!!
y = x
Subtract y from both sides.
0 = x - y switcheroo.
x - y = 0 Done!

Re: Area problems Please Help!!
Although I beg to differ, I will take that as a complement. 
Quick question, I have one like we just did, only one of the points are 0's. Do I need to modify equation in any way since they are zeros?

Re: Area problems Please Help!!
Kay.
So slope first? We have (0 , 0) , (4 , -4)?
(y2-y1) / (x2-x1)
(-4-0) / (4-0)
-4 / 4
= -1?

Correct. m = slope = -1

Re: Area problems Please Help!!
okay so from there we get:
y - 0 = -1 ( x - 4)
y - 0 ( x - 4)
so x - y = 4?

Hi;
Nope! Try plugging in your points.

Re: Area problems Please Help!!
Your points are ( 0 , 0 ) and ( 4 , - 4). First one is the x coordinate second one is the y coordinate.
using the first point ( x = 0 , y = 0 ) plug in to your answer.
x - y = 4
0 - 0 = 4 is not true, your equation is wrong.

Re: Area problems Please Help!!
Oh I see now, that makes sense. okay.
y - 0 = x - 0
x - y = 0?

Does that work when you check, by plugging in points?

4--4 = 8, not zero, so I guess I'm way off!

You have made a careless error right here:
y - 0 = x - 0
