Question

you want to find the treasure located on the map at x. you are located at ●. the following transformations will lead you to the treasure, but they are not in the correct order. find the correct order. use each transformation exactly once. • rotate 180° about the origin. • reflect in the y-axis. • rotate 90° counterclockwise about the origin. • translate 1 unit right and 1 unit up.

Explanation:

Step1: Analyze each transformation

- **Rotate \(90^{\circ}\) counter - clockwise about the origin**:
Let the initial point (green dot) be \((x,y)\). The rule for a \(90^{\circ}\) counter - clockwise rotation about the origin is \((x,y)\to(-y,x)\).
- **Reflect in the \(y\) - axis**:
The rule for reflecting a point \((x,y)\) in the \(y\) - axis is \((x,y)\to(-x,y)\).
- **Rotate \(180^{\circ}\) about the origin**:
The rule for a \(180^{\circ}\) rotation about the origin is \((x,y)\to(-x,-y)\).
- **Translate \(1\) unit right and \(1\) unit up**:
The rule for translation is \((x,y)\to(x + 1,y+1)\).

Assume the green - dot has coordinates \((3,-1)\) (by counting the grid squares from the origin).
- After rotating \(90^{\circ}\) counter - clockwise about the origin: \((3,-1)\to(1,3)\) (using \((x,y)\to(-y,x)\)).
- After reflecting in the \(y\) - axis: \((1,3)\to(-1,3)\) (using \((x,y)\to(-x,y)\)).
- After rotating \(180^{\circ}\) about the origin: \((-1,3)\to(1,-3)\) (using \((x,y)\to(-x,-y)\)).
- After translating \(1\) unit right and \(1\) unit up: \((1,-3)\to(2,-2)\) (not the \(X\) position).

Let's start with the correct order:
1. **Reflect in the \(y\) - axis**:
If the green - dot is \((3,-1)\), after reflection in the \(y\) - axis, it becomes \((-3,-1)\) (using \((x,y)\to(-x,y)\)).
2. **Rotate \(90^{\circ}\) counter - clockwise about the origin**:
Using the rule \((x,y)\to(-y,x)\) on \((-3,-1)\), we get \((1,-3)\).
3. **Translate \(1\) unit right and \(1\) unit up**:
Using the rule \((x,y)\to(x + 1,y + 1)\) on \((1,-3)\), we get \((2,-2)\) (incorrect).

Let's try another order:
1. **Rotate \(90^{\circ}\) counter - clockwise about the origin**:
For the green - dot \((3,-1)\), using \((x,y)\to(-y,x)\), we get \((1,3)\).
2. **Translate \(1\) unit right and \(1\) unit up**:
Using \((x,y)\to(x + 1,y+1)\) on \((1,3)\), we get \((2,4)\) (incorrect).

Let's try:
1. **Translate \(1\) unit right and \(1\) unit up**:
For the green - dot \((3,-1)\), we get \((4,0)\).
2. **Rotate \(90^{\circ}\) counter - clockwise about the origin**:
Using \((x,y)\to(-y,x)\) on \((4,0)\), we get \((0,4)\) (incorrect).

Let's use the correct geometric transformation order:
1. **Reflect in the \(y\) - axis**:
Let the green - dot be \((3,-1)\), after reflection \((-3,-1)\).
2. **Translate \(1\) unit right and \(1\) unit up**:
Using \((x,y)\to(x + 1,y + 1)\) on \((-3,-1)\), we get \((-2,0)\).
3. **Rotate \(90^{\circ}\) counter - clockwise about the origin**:
Using \((x,y)\to(-y,x)\) on \((-2,0)\), we get \((0,-2)\) (incorrect).

Let's assume the green - dot is \((2,-1)\) (by re - counting).
1. **Reflect in the \(y\) - axis**: \((2,-1)\to(-2,-1)\).
2. **Rotate \(90^{\circ}\) counter - clockwise about the origin**: \((-2,-1)\to(1,-2)\).
3. **Translate \(1\) unit right and \(1\) unit up**: \((1,-2)\to(2,-1)\) (incorrect).
