Hi Tammy;
y=x-2;(3,1) (-2,-4)
Let's begin with the first coordinates...
(3,1)-----(x,y)
The equation is...
y=x-2
1=3-2
1=1
SOLVED!

(-2,-4)
y=x-2
-4=-2-2
-4=-4
SOLVED!

Do you know how to graph these?

I am not really sure how to graph. Do I graph (3,1) and (-2,-4)
You will graph both...

4
3
2
1       *
-4 -3 -2 -1 0 1 2 3 4---x-axis
-1
-2
-3
*    -4

y
axis

(3,1) (x,y) are both positive numbers.  The x-axis is the horizontal axis.  The y-axis is vertical.  First, you will find 3.  It is on the right of the center of the graph.  Then, you will move up to find 1.

(-2,-4) (x,y) are both negative numbers.  First, you will find -2.  It is to the left of the center.  Then, you will find -4.  It is below.
