A transformation

$T:(x,y)\rightarrow (x+3,y+1)$

is a translation 3 units to the right and 1 unit up.

To find the image of point B(4,1), you have to substitute 4 instead of x and 1 instead of y into the transformation rule:

$(4,1)\rightarrow (4+3,1+1).$

Then the image point has coordinates (4+3,1+1) that is (7,2).

Answer: correct choice is A
