Final answer:
To plot the point (3, 4) on a Cartesian coordinate system, you must move three places horizontally to the right and then four places vertically upwards, which makes the statement false.
Step-by-step explanation:
The statement to plot the point (3, 4) on a scatter plot, move three places vertically and four places horizontally is False. When plotting a point in a Cartesian coordinate system, you move horizontally first and then vertically. Therefore, to plot the point (3, 4), you need to move three places horizontally to the right (along the x-axis) and then four places vertically upwards (along the y-axis).
