Answer:
The coordinates of her new position are (0 , -5) ⇒ answer B
Step-by-step explanation:
* Lets revise some translation
- If the point (x , y) translated horizontally to the right by h units
then the new point = (x + h , y)
- If the point (x , y) translated horizontally to the left by h units
then the new point = (x - h , y)
- If the point (x , y) translated vertically up by k units
then the new point = (x , y + k)
- If the point (x , y) translated vertically down by k units
then the new point = (x , y - k)
* Now lets solve the problem
∵ Nancy start from position (2 , -3)
- She walks 5 blocks to the right and 3 blocks down
∴ Add x-coordinate by 5 and subtract y-coordinate by 3
∵ The starting position is (2 , -3)
∴ The new position is (2 + 5 , -3 - 3) = (7 , -6)
- She walks 7 blocks to the left and 1 block up
∴ Subtract x-coordinate by 7 and add the y-coordinate by 1
∴ The new position is (7 - 7 , -6 + 1) = (0 , -5)
* The coordinates of her new position are (0 , -5)
