A horizontal number line has a point that is 6 units to the right of 0. Where should this same number be found on a vertical number line?
A: 6 units left
B: 6 units right
C: 6 units down
D: 6 units up
The correct answer is D: 6 units up.
On a horizontal number line, moving to the right indicates positive values, while moving to the left indicates negative values. Therefore, if a point is 6 units to the right of 0, its value is positive 6.
On a vertical number line, moving up indicates positive values, while moving down indicates negative values. So, if the same point is to be found on a vertical number line, it would be 6 units up.
