If a figure is dilated by a scale factor of 4, what will be the coordinates of the image of T(-4, 2)? T'(-1, ) T'(-16, 8) T'(-1, 8) T'(-16, )

Respuesta :

Answer:

The correct choice is [tex]T'(-16,8)[/tex]

Step-by-step explanation:

The mapping for a dilation by a scale factor of k is:

[tex](x,y)\to (kx,ky)[/tex]

If a figure is dilated by a scale factor of 4, then k=4.

To find the coordinates of the image of T(-4,2), we substitute x=-4 and y=2 into the rule to obtain:

[tex]T(-4,2)\to T'(4x\times -4,4\times2)[/tex]

[tex]\implies T(-4,2)\to T'(-16,8)[/tex]

The correct choice is [tex]T'(-16,8)[/tex]
