Question

What coordinate expression represents the coordinates of any point after dilation by a scale factor of 2

Answer 1

Answer:

When figure ABCD is dilated by a scale factor of 2, the coordinates of all the points in the dilated figure are multiplied by 2. If (x, y) is any point on the original figure that gets dilated by a scale factor of 2, then the expression that represents the coordinates of this point in the dilated figure is given by (2x, 2y)

Step-by-step explanation:

Answer 2

Answer: (x,y) → (2x,2y) .

Step-by-step explanation:

• A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.

If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).

So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of 2:

(x,y) → (2x,2y) .
