Step-by-step Solution
To plot the points \( A(2, 3) \), \( B(5, -3) \), and \( C(-4, 2) \) on a coordinate plane, you can follow these steps:
1. **Plotting the Points:**
- Point \( A(2, 3) \): Start at the origin (0, 0), move 2 units to the right (positive x-direction), and then move 3 units up (positive y-direction). Mark this point as \( A \).
- Point \( B(5, -3) \): From the origin, move 5 units to the right and then 3 units down (negative y-direction). Mark this point as \( B \).
- Point \( C(-4, 2) \): From the origin, move 4 units to the left (negative x-direction) and then 2 units up. Mark this point as \( C \).
2. **Translating Point A:**
- The translation involves moving point \( A \) 5 places down and 4 places left.
- The original coordinates of point \( A \) are \( (2, 3) \).
- Moving 5 places down means subtracting 5 from the y-coordinate: \( 3 - 5 = -2 \).
- Moving 4 places left means subtracting 4 from the x-coordinate: \( 2 - 4 = -2 \).
- Therefore, the new coordinates of point \( A' \) after the translation are \( (-2, -2) \).
3. **Naming the Image:**
- The image of point \( A \) after the translation is \( A'(-2, -2) \).
Now you can plot the new point \( A' \) on the coordinate plane as well.
Quick Answer
Plot points \( A(2, 3) \), \( B(5, -3) \), and \( C(-4, 2) \). Translate \( A \) 5 down and 4 left to get \( A'(-2, -2) \).
