-2x - 2
Well, that cross you see on the graph are your X and Y lines.
X line is flat on its side, Y line goes up to the sky!
-2x - 2 are what you need most to start graphing. Ignore y> for now.
-2x tells you your slope, or how steep your line is. And whether your line will shoot up, or go down.
Since its NEGATIVE ( - 2 x) your line will most definetely be going DOWN.
2x tells you your slope. Or how steep the line will be.
But FIRST, you need to know where your line begins.
thats what -2 is for.
See those little numbers on Y line?
Look for -2 on the line.
Thats where your line begins.
Make a little dot there.
Now -2x tells you the slope of the line, or how steep it is.
Take the -2.
Put a 1 under it for no reason. You will do this every single time in the future.
Now you Have
-2 / 1
That tells you the slope.
Since the line is NEGATIVE:
You go DOWN 2, and RIGHT 1.
