Question

angle abc is translated 9 units to the right and 5 units up. the result is △abc, as shown below. (a) the arrows below show that the coordinates on the left are mapped to the coordinates on the right. fill in the blanks to give the coordinates after the translation. original coordinates → final coordinates a(-7, -4) → a(□, □) b(-8, -1) → b(□, □)

Explanation:

Step1: Translate point A

Add 9 to x-coordinate, 5 to y-coordinate: $-7+9=2$, $-4+5=1$

Step2: Translate point B

Add 9 to x-coordinate, 5 to y-coordinate: $-8+9=1$, $-1+5=4$

Answer:

$A'=(2,1)$
$B'=(1,4)$
