Question

you start at (0, -4). you move up 3 units and down 4 units. where do you end?

Explanation:

Step1: Calculate the new y - coordinate after moving up

The starting point is $(0, - 4)$. Moving up 3 units means adding 3 to the y - coordinate. The new y - coordinate is $-4 + 3=-1$.

Step2: Calculate the final y - coordinate after moving down

After getting $y=-1$, moving down 4 units means subtracting 4 from the y - coordinate. So, $-1-4=-5$. The x - coordinate remains 0 as there is no horizontal movement.

Answer:

$(0, - 5)$
