Question

Graph

The triangle shown is a pre-image.

Apply a scale factor of 1/2 to find the image of point A.
(0, 0)
(3, –2.5)
(0, –2.5)
(0, –10)

Answer 1

the answer C

Explanation:

Answer 2

Correct choice is C

Explanation:

A dilation by a factor
`(1)/(2)` with the center of dilation at origin has the rule:

`(x,y)\mapsto \left((x)/(2),(y)/(2)\right).`

If pre-image point A has coordinates (0,-5) (from the diagram), then the image point A' will have coordinates

`\left((0)/(2),(-5)/(2)\right)=\left(0,-2.5\right).`
