Question

What are the coordinates of the image of the point (2, –4) after a dilation with a center of (0, 0) and scale factor of 4?

A.
(0, 0)
B.
C.
(2, –4)
D.
(8, –16)

Answer 1

c i think....but whats the number for b

Answer 2

The required coordinate of the point is (8, -16).

Dilation

It means to magnify into bigger or demagnify into small things for our convenience.

Given

Point (2, -4)

Dilation = 4

Formula

$\rm Point\ (x*dilation,\ y* dilation )$

How to find the coordinate after dilation?

Point ( x, y) = (2, -4)

Dilation = 4

Then

$\rm Point\ (x*dilation,\ y* dilation )\\\rm Point\ (2*4,\ -4*4 )\\\rm Point\ (8, -16)$

Thus, the required coordinate of the point is (8, -16).
