Let's walk through the exercise step-by-step.
Step 1: Original Coordinates
You are asked to plot the original points of your house in the new housing development:
- A(2, 2)
- B(4, 2)
- C(4, 4)
- D(3, 5)
- E(2, 4)
Make sure to place these points accurately on the graph provided.
Step 2: Moving Your House
Next, you need to calculate the new coordinates after the flood, which moves your house 4 blocks to the left and 2 blocks down.
To calculate the new coordinates:
-
For Point A(2, 2):
- New x-coordinate = 2 - 4 = -2
- New y-coordinate = 2 - 2 = 0
- → A(-2, 0)
-
For Point B(4, 2):
- New x-coordinate = 4 - 4 = 0
- New y-coordinate = 2 - 2 = 0
- → B(0, 0)
-
For Point C(4, 4):
- New x-coordinate = 4 - 4 = 0
- New y-coordinate = 4 - 2 = 2
- → C(0, 2)
-
For Point D(3, 5):
- New x-coordinate = 3 - 4 = -1
- New y-coordinate = 5 - 2 = 3
- → D(-1, 3)
-
For Point E(2, 4):
- New x-coordinate = 2 - 4 = -2
- New y-coordinate = 4 - 2 = 2
- → E(-2, 2)
So the new coordinates after the flood are:
- A(-2, 0)
- B(0, 0)
- C(0, 2)
- D(-1, 3)
- E(-2, 2)
Identifying the Correct Choice
Among the given choices for the new coordinates, the correct answer is:
- A(-2, 0), B(0, 0), C(0, 2), D(-1, 3), E(-2, 2)
Step 3: Plot the New Coordinates
You would now plot these new coordinates on the graph.
Step 4: Doubling the Size of the House
Now, you want to double the size of your house using the new coordinates after the flood. Each coordinate will be multiplied by 2:
New coordinates:
- A(-2, 0) → (-22, 02) = (-4, 0)
- B(0, 0) → (02, 02) = (0, 0)
- C(0, 2) → (02, 22) = (0, 4)
- D(-1, 3) → (-12, 32) = (-2, 6)
- E(-2, 2) → (-22, 22) = (-4, 4)
The new coordinates after doubling are:
- A(-4, 0)
- B(0, 0)
- C(0, 4)
- D(-2, 6)
- E(-4, 4)
Choices for the New Coordinates
From the previous calculations, the possible answers (using the doubling coordinates) are:
- A(-4, 0)
- B(0, 0)
- C(0, 4)
- D(-2, 6)
- E(-4, 4)
This does not directly match the answer choices given (4,4), (6,10), (4,8), (8,8), (8,4) — it seems like a misunderstanding of the problem setup, or the answer choices listed do not directly correlate to these new coordinates. If you need a specific choice, focus on what aligns correctly with the transformations discussed.
Step 5: Plotting the Final Coordinates
Lastly, plot these new coordinates on the graph to show how the size of your house was enlarged through dilation.
Explanation of Dilation
Dilation in this context refers to scaling the coordinates of your house by a factor of 2 while maintaining the relative positions. It enlarges the shape of the house without changing its proportions or basic structure. Each point of the house moves away from the origin proportionally, creating a larger version of the original house shape.
Make sure to compare this new plot with the original coordinates to visualize the difference in size after the dilation.
