Point a is located at (? 5, 2) on a coordinate grid. point a is translated 1 unit to the left and 5 units down to create point a'. which measurement is closest to the distance between point a and point a' in units? a) 4.7 units b) 4.9 units c) 5.1 units d) 5.3 units

ANSWER

C) 5.1 units

EXPLANATION

The coordinates of A are (5,2).

If this point is translated 1 unit to the left and 5 units down to create point A'.

Then A' has coordinates





The distance between A and A' is calculated using the distance formula,









We round to the nearest tenth to obtain,



The measurement that is closed to the distance is 5.1 units
