Answer:
A' (1,0), B'(0,3), C' (-2,2)
Explanation:
Let's do exactly what it says: the new x becomes x-3, so it's 3 units less than before. The second coordinate is y-1, so one less
The first coordinates then become 2-3=-1, 3-3=0, and 1-3= -2
The second coordinate becomes 1-1= 0, 4-1=3, and 3-1= 2
The new points are A' (1,0), B'(0,3), and C' (-2,2)
