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?
Vivian L.
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.
