Since the slope of the graph is positive (mainly positive 1/2), y is going to increase as you increase x If we start at x=0, then y = 2, and if we increase this at all, say move to x=8, y = 2, which is bigger than what we previously had which was y=2 Therefore, we can conclude that the plot should increase from left to right
