Question

What will be the coordinates of vertex N' of the image? (-2, 4) (-2, 6) (-4, 4) (-4, 8)

Answer 1

Option B is correct (-2,6)

Answer 2

`N'(-2,6)`

Explanation:

To Dilate is to enlarge or to shrink a figure. Since the Center of Dilation is the Point P. We'll dilate and add each value of each coordinate.

`Dx=2(x,y) \\P(2,-2)\Rightarrow D_( P centered)=(2x+2,2y-2)`

`M(-1,-2) \Rightarrow M'=(2(-1)-2,2(-2)+2)= (-4,-2)\\\\N(0,2) \Rightarrow N'= (2(0)-2,2(2)+2) = (-2,6)\\\\P(2,-2) \Rightarrow P'=(2(2)-2,2(-2)+2)=(2,-2)`
