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