Q:

Which transformation was applied to figure A to form figure B? A. Figure A was translated 3 units right and 10 units down to form figure B. B. Figure A was translated 10 units right and 3 units down to form figure B. C. Figure A was reflected across the line m to form figure B. D. Figure A was rotated 90Β° clockwise about the point N to form figure B.

Accepted Solution

A:
Answer:BStep-by-step explanation:Let point N has coordinates (0,0), then figure A has vertices at points (-3,0), (-7,0), (-7,4) and (-3,4). Figure B has vertices at points (3,1), (7,1), (7,-3) and (3,-3).1. Translation 10 units to the right has the rule (x,y)β†’(x+10,y).Then vertices of the figure A have images:(-3,0)β†’(7,0);(-7,0)β†’(3,0);(-7,4)β†’(3,4);(-3,4)β†’(7,4).2. Translation 3 units down has the rule(x,y)β†’(x,y-3).Then images are(7,0)β†’(7,-3);(3,0)β†’(3,-3);(3,4)β†’(3,1);(7,4)β†’(7,1).As you can see these points are exactly the vertices of the figure B.
