Answer:
-3/2
Step-by-step explanation:
Use formula (y2 - y1)/(x2 - x1)
Take points (-8, 4) and (-6, 1)
Use the formula:
y2 = 1
y1 = 4
x2 = -6
x1 = -8
(1 - 4)/(-6 - (-8))
= -3/(-6 + 8)
= -3/2

Step-by-step explanation:
first find the perimeter of both triangles
Original perimeter: 72 in
scaled perimeter: 24 in
A is wrong since the scaled perimeter is actually smaller.
B is wrong because its not 6 times smaller
C is wrong since it's not 1/9 of the original
D is correct since the scaled is a 1/3 of the original perimeter (72*1/3 = 24)
