Question

square abcd was translated using the rule (x, y)→(x - 4, y + 15) to form abcd. what are the coordinates of point d in the pre - image if the coordinates of point d in the image are (9, - 8)? (5, 7) (-6, -4) (13, -23) (18, 1)

Explanation:

Step1: Set up x - coordinate equation

$x - 4=9$, so $x = 9 + 4=13$.

Step2: Set up y - coordinate equation

$y + 15=-8$, so $y=-8 - 15=-23$.

Answer:

$(13, -23)$
