point G (-7,4) is translated using the rule (x + 10, y - 6)....
so x coordinate of G' = (-7 + 10) = 3 <== ur just adding ur x coordinate of point G (which is -7) to 10...giving u ur x coordinate of point G'
and y coordinate of G' = (4 - 6) = -2...because ur adding ur y coordinate of point G (which is 4) to -6 giving u ur y coordinate of point G'
answer is : 3
