This is a linear (straight line) graph. To draw it, the easiest way is to draw a line through its intercepts.
For x-intercept, plug in y=0: 0=-x+2, so x=2 (the point (2,0)).
For y-intercept, plug in x=0: y=0+2=2 (the point (0,2)). When the line is drawn, it slopes backwards as it passes through the intercepts.
