Question

you move right 3 units. you end at (5, 1). where did you start?

Explanation:

Step1: Analyze the movement on the x - axis

When moving right on the coordinate plane, the x - coordinate increases. If we end at an x - coordinate of 5 after moving right 3 units, we need to find the original x - coordinate by subtracting the number of units moved from the final x - coordinate. Let the original x - coordinate be \(x\). The formula is \(x=\text{final }x - \text{units moved}\). So \(x = 5-3=2\).

Step2: Analyze the movement on the y - axis

Since we only moved horizontally (right), the y - coordinate does not change. The final y - coordinate is 1, so the original y - coordinate is also 1.

Answer:

\((2, 1)\)
