Answer:
Explanation:
To find the result of a dilation, you need to multiply each coordinate of the original point by the dilation factor.
In this case, the dilation factor is 3. So to dilate the point (5, -4), you need to multiply both the x-coordinate and y-coordinate by 3.
So the result of the dilation is:
(5 * 3, -4 * 3) = (15, -12)
Therefore, the point (5, -4) after a dilation of 3 is (15, -12).
