Plug in some values for x to get an idea of what points are on the curve. For example, when x=0, we get y=2. When x=1, we get y=0. We can plot these points on a graph. The function that you are graphing is linear, so as long as we know two points, we can make a straight line going through them for the graph. It looks like this:
Some key points to notice: this is in slope-intercept form.
The slope is -2. Since the slope is negative, when you go to the right, the graph will go down. In particular, when you go right 1 unit, you go down 2 units to stay on the curve.
The +2 part gives you the y-intercept. That is, the graph crosses the y-axis at y=2.
