Question

value: 7
what will the coordinates of triangle rst be after it is translated 4 units down and 3 units left?
o a. r(-1,-2), s(8,-1), t(5,-9)
o b. r(-7,-2), s(8,-1), t(-1,-1)
o c. r(-1,6), s(8,7), t(5,-1)
o d. r(-7,-2), s(2,-1), t(-1,-9)

Explanation:

Step1: Identify original coordinates

From the graph: $R(-4,2)$, $S(5,3)$, $T(2,-5)$

Step2: Apply translation rule

Left 3 units: $x-3$; Down 4 units: $y-4$
$R': (-4-3, 2-4)=(-7,-2)$
$S': (5-3, 3-4)=(2,-1)$
$T': (2-3, -5-4)=(-1,-9)$

Answer:

d. R(-7, -2), S(2, -1), T(-1, -9)
