Answer: The coordinates of A = (-6,-3).
Explanation:
The coordinates of image of point (x,y) after the dilation with scale factor of k given by :-

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

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