Any given point on a graph follows the format (x,y). In this case, the x-value is 4 and the y-value is 0. We know that the horizontal axis is the x-axis (left and right movement) and the vertical axis is the y-axis (up and down movement). We can use this knowledge to find the point (4,0).
Starting at (0,0), we move 4 spaces to the right (x-value) and 0 spaces up/down (y-value). This leaves us in a position much like that of Point B on the graph above. Therefore, the point closest to (4,0) is Point B.
