Final answer:
To dilate triangle KLM with a scale factor of 2, multiply the x and y coordinates of each point by 2. The coordinates of K' are (-4, 2).
Step-by-step explanation:
To dilate triangle KLM with a scale factor of 2, we need to multiply the x-coordinates and y-coordinates of each point by 2.
K' has the same x-coordinate as K, which is -2, multiplied by 2, giving us -4.
K' has the same y-coordinate as K, which is 1, multiplied by 2, giving us 2.
Therefore, the coordinates of K' are (-4, 2).
