**Title: Translating a Quadrilateral on the Coordinate Plane**
**Instruction:**
Draw the image of quadrilateral \(ABCD\) under the translation \((x, y) \rightarrow (x-7, y+1)\).
**Graph Explanation:**
- The graph is a coordinate plane with axes labeled \(x\) and \(y\), ranging from -7 to 7 on both axes.
- A light grid pattern covers the entire plane to assist with plotting points and shapes.
- The quadrilateral \(ABCD\) is plotted on the plane.
**Initial Quadrilateral \(ABCD\):**
- Points are approximately at:
- \(A(1, 1)\)
- \(B(1, 4)\)
- \(C(4, 4)\)
- \(D(4, 1)\)
- This quadrilateral is shaded lightly in green and is positioned in the upper right quadrant.
**Transformed Quadrilateral \(A'B'C'D'\):**
- The translation moves each point 7 units left and 1 unit up:
- \(A'(1-7, 1+1) = (-6, 2)\)
- \(B'(1-7, 4+1) = (-6, 5)\)
- \(C'(4-7, 4+1) = (-3, 5)\)
- \(D'(4-7, 1+1) = (-3, 2)\)
- The transformed quadrilateral is plotted and shaded in blue, positioned in the lower left quadrant.
**Conclusion:**
This exercise demonstrates how each vertex of a shape on the coordinate plane is altered through translation. Understanding translations is essential for grasping more complex geometrical transformations. Remember to adjust both \(x\) and \(y\) coordinates according to the translation instructions provided.
