Answer:
The coordinates of point C after dilation will be: (3,-1)
Step-by-step explanation:
Dilation in the coordinate plane can be defined as enlargement. There are different types of dilation. The most simple one is dilation from origin.
A factor is used to dilate a point from the origin. For example, if (x,y) is a point and a is the scale factor then the coordinates of points will be:
(x,y) => (ax,ay)
Given point is:
C(6,-2)
r = 1/2
The new coordinates of point C will be:
![C(6,-2) => C'(\frac{1}{2}(6) , \frac{1}{2}(-2)) => (3,-1)](https://tex.z-dn.net/?f=C%286%2C-2%29%20%3D%3E%20C%27%28%5Cfrac%7B1%7D%7B2%7D%286%29%20%2C%20%5Cfrac%7B1%7D%7B2%7D%28-2%29%29%20%3D%3E%20%283%2C-1%29)
The coordinates of point C after dilation will be: (3,-1)
A reflection is a transformation where the mirror image of a figure is shown directly opposite its line of reflection.
To find an image that has been reflected across the line y = x, switch the x- and y-coordinates.
Therefore, the rule for reflecting an image across the line y = x can be described as (x, y) → (y, x).
Now, apply rule to coordinates ABC:
A': (2, 3)
B': (1, -4)
C': (-2, -3)
