Answer:
C) (x, y) ⇒ (x -3, y -4), (5, -1)
Explanation:
You know that the x-coordinate measures how far to the right of the y-axis a point is. If the point is moved 3 units left, it will be 3 fewer units to the right of the y-axis. That is, its x-coordinate will have changed from x to x-3.
Similarly, moving a point down 4 units reduces its y-coordinate by 4 units, so that y becomes y-4.
Together, these transformations are ...
(x, y) ⇒ (x -3, y -4) . . . . . . matches choice C
