Question

Triange ABC goes through a dilation with a scale factor of 1.5. If the coordinates of A are at (-4, -2) what will the coordinates of A' be?

Answer 1

Answer: The coordinates of A = (-6,-3).

Step-by-step explanation:

The coordinates of image of point (x,y) after the dilation with scale factor of k given by :-

$(x,y)\to (kx,ky)$

Given: Scale factor = 1.5

Coordiantes of A = (-4,-2)

The coordiantes of A' after a dilation with a scale factor of 1.5 will be

$(1.5\times-4, 1.5\times-2) = (-6,-3)$

Hence, the coordinates of A = (-6,-3).
