Question

you move up 4 units. you end at (-4, 1). where did you start?

Explanation:

Step1: Analyze the move (assuming up 4 units)

If we moved up 4 units to reach \((-4, 1)\), we need to reverse the move. Moving up means adding to the y - coordinate, so to find the start, we subtract 4 from the y - coordinate of the end point. The x - coordinate remains the same as there is no horizontal move mentioned (assuming only vertical move up 4).
The end point is \((x,y)=(-4,1)\). For the y - coordinate of the start point: \(y_{start}=1 - 4=- 3\). The x - coordinate \(x_{start}=-4\) (since no horizontal movement).

Step2: Determine the start point

So the start point has x - coordinate \(-4\) and y - coordinate \(-3\).

Answer:

\((-4, - 3)\)
