Question

you start at (0, 3). you move up 1 unit and down 1 unit. where do you end?

Explanation:

Step1: Move up 1 unit

In a coordinate - system, moving up means increasing the y - coordinate. Starting at the point $(0,3)$, when we move up 1 unit, the new y - coordinate is $3 + 1=4$. So the point becomes $(0,4)$.

Step2: Move down 1 unit

Moving down means decreasing the y - coordinate. Starting from the point $(0,4)$, when we move down 1 unit, the new y - coordinate is $4-1 = 3$. The x - coordinate remains 0 throughout the vertical movement. So the final point is $(0,3)$.

Answer:

$(0,3)$
