The given translation rule tells that for every vertex we should add 1 to the x-coordinate and subtract 2 from the y-coordinate.
A'(3,-3), B'(1,2), C'(-2,3)
Practice makes perfect
We are given the vertices of â–ł ABC and a translation rule.
(x,y) → (x+ 1,y- 2)
To find the coordinates of the vertices of the image, we need to add 1 to the x-coordinates and subtract 2 from the y-coordinates of the vertices of the preimage.
ccccc
(x,y) &→ &(x+ 1,y- 2) & → & (x',y')
A(2,-1) &→ & (2+ 1,-1- 2) &→ & A'(3,-3)
B(0,4) &→ & (0+ 1,4- 2) &→ & B'(1,2)
C(-3,5) &→ & (-3+ 1,5- 2) &→ & C'(-2,3)
