It is given in the question that
Point N(7, 4) is translated 5 units up.
And we have to find the coordinates of its image after this transformation.
Since the point translated up by 5 units, so the x coordinate remains same and we have to add 5 to y coordinate.
So the new coordinate after the transformation is
[tex]N'(7+5,4)
\\
N'(12,4)[/tex]
And that's the required coordinate after the given transformation .
