Question

3. Find the horizontal change and the vertical change for the translation.

P(4, -4) ----> (-4, 7)
A. right 8; up 11
B. left 8; down 11
C. right 8; down 11
D. left 8; up 11

4. the point C(3, -1) is translated to the left 4 units and up 1 unit.
a. write the rule for the translation
b. what are the coordinates of the image point?
A. (x,y)--> (x+4+1); (7, -2)
B. (x, y) --> (x-4, y -1); (-1, 0)
C. (x,y)---> (x+4, y -1); (7, 0)
D. (x,y) ---> (x-4, y+1); (-1,0)

5.

Answer 1

P(4, -4) ----> (-4, 7)
x- axis from 4 to -4 ; move to the left 8 units.
y-axis from -4 to 7 ; move up 11 units

D. left 8; up 11

C(3, -1) translated to the left 4 units and up 1 unit.
from 3 of x-axis move to the left 4 units to arrive at -1
from -1 of y-axis move up 1 unit is to arrive at 0.

(xy) → (x-4, y + 1) (-1,0) Choice D.
