Answer:
Second option: On a coordinate plane, rectangle A'B'C'D' prime has points
(See the graph attached)
Step-by-step explanation:
For this exercise it is importnat to know that a Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) has the same shape as the Pre-Image (which is the original figure before the transformation), but they have different sizes.
In this case, you know that the vertices of the rectangle ABCD ( The Pre-Image) are the following:

Therefore, to find the vertices of the rectangle A'B'C'D' (The Image) that results of dilating the rectangle ABCD by a factor of 4 about the origin, you need to multiply the coordinates of each original vertex by 4. Then, you get:

Finally, knowing those points, you can identify that the graph that shows the result of that Dilation, is the one attached.
You have to complete the square. When you do this you get an equation that looks like this: (x-3)^2 + (y+4)^2 = 4. So your center is (3, -4) and your radius is 2. That looks like B to me!!!

20%
Step-by-step explanation:
400/2000=0.2
0.2*100=20
Answer:
y = 1/3x - 10/3
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of one another so m = -1/3
Given (-1,-3)
y = mx + b
-3 = -1/3(-1) + b
-9/3 = 1/3 + b
b = -10/3
so y = 1/3x - 10/3
