Question

Point W has coordinates (4, -7). If it is translated left 4 units, what are the coordinates of its image? (4, -11) (0, -7) (0, -11) (4, -3)

Answer 1

(0,-7)

Explanation:

4-4 = 0, therefore (0, -7) is your answer since we are translating on the x axis

Answer 2

(0,-7)

EXPLANATION

Point W has coordinates (4, -7).

We want to find the image of this point after it has been left 4 units.

The mapping will be

`(x,y)\to (x-4,y)`

This implies that

`(4, - 7)\to (4-4, - 7)`

This simplifies to

`(4, - 7)\to (0, - 7)`

The correct choice is B.
