We can choose any two points on the line, but it is easiest to use the intercepts. When x = 0, y = 0 * 2 = 0. So the point (0,0) is on the line. When y = 2, we have 2 = 2x, so x = 1. The point (1,2) is also on the line. The slope of the line is the change in y divided by the change in x, which is (2-0)/(1-0) = 2. Therefore, the slope of the line is 2.
