Question

Figure ABC is to be translated to Figure A'B'C' using the rule (x, y) → (x−3, y+4).

Which coordinates will best represent point A'?

a. (−2, 5)
b.(4, −3)
c. (−2, −3)
d. (4, 5)

Answer 1

Option a is correct

(-2, 5)

Step-by-step explanation:

As per the statement:

Figure ABC is to be translated to Figure A'B'C'

Using the rule:

`(x,y) \rightarrow (x-3, y+4)`

We have to find the coordinates will best represent point A'.

From the given triangle ABC:

Coordinate of A = (1, 1)

Apply the rule on ABC we have;

`A(1,1) \rightarrow (1-3, 1+4)=A'(-2, 5)`

therefore, the coordinates will best represent point A' is, (-2, 5)

Answer 2

Answer:
(-2,5)

Step-by-step explanation:
We are given the following translation rule:
(x,y) .............> (x-3 , y+4)
This means that:
new x coordinate can be found by subtracting 3 from the old x coordinate
new y coordinate can be found by adding 4 to the old y coordinate

From the figure, we can note that the coordinates of point A are (1,1).

Applying the above translation rule, we can get the coordinates of A' as follows:
x coordinate of A' = x coordinate of A - 3
x coordinate of A' = 1 - 3 = -2

y coordinate of A' = y coordinate of A + 4
y coordinate of A' = 1 + 4 = 5

Based on the above, the coordinates of A' would be (-2,5)

Hope this helps :)
