Answer:
New x-coordinate: 4
New y-coordinate: 5
New point: (4,5)
Explanation:
You know that the coordinates of a point of this triangle are the following:

And you know that it is dilated with a scale factor of
, then, to find the new coordinates of the point, you need to multiply the original coordinates by the scale factor:
New x-coordinate:



New y-coordinate:



The new point is (4,5)
