Answer:
C
Step-by-step explanation:
C: x + y = -4
Given:
The point (5,0) dilated by a scale factor of 3 centered at the origin.
To find:
The coordinates of image.
Solution:
If a figure dilated by a scale factor of k centered at the origin, then the rule of transformation is
![(x,y)\to (kx,ky)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Cto%20%28kx%2Cky%29)
The point is dilated by a scale factor of 3 centered at the origin, then the rule of transformation is
![(x,y)\to (3x,3y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Cto%20%283x%2C3y%29)
The given point is (5,0). Putting x=5 and y=0, we get
![(5,0)\to (3(5),3(0))](https://tex.z-dn.net/?f=%285%2C0%29%5Cto%20%283%285%29%2C3%280%29%29)
![(5,0)\to (15,0)](https://tex.z-dn.net/?f=%285%2C0%29%5Cto%20%2815%2C0%29)
Therefore, the image of (5,0) is (15,0).
