Answer:
Check below
Step-by-step explanation:
That's too bad you haven't attached a rectangle.
Here's an example, with the data you've typed in.
1) When we dilate a rectangle we either grows it or shrink it through a scale factor.
Check the first picture below.
The New Dilated Rectangle A'B'C'D' will follow its coordinates, when the <u>Center of Dilation is at its origin(Middle):</u>
2) But In this question, <u>B is the center of Dilation</u>. So, Since B is the Dilation Point B=B' . And More importantly:
3) So check the pictures below for a better understanding.
Answer:
(-6, 6), (2, 6), (-6, -2), (2, -2)
Step-by-step explanation:
Unfortunately, you can't just multiply the coordinates of the corners by 4. That works if the center of the enlargement is the origin, (0, 0). So you have to do this enlargement in 3 steps for <u>each</u> of the corner points.
Step 1 Move the point right 2 units and down 2 units <em>.</em>
The reason for this step is that this is what you do to move the center (-2, 2) to (0, 0).
Step 2 Multiply the new coordinates by 4.
Step 3 Move the new point left 2 units and up 2 units .
Example: using the upper-left corner (-3, 3)...
Step 1
Step 2
Step 3
Repeat the process with the other three corners.
