Answer:
-1
Step-by-step explanation:
The slope formula works nicely for this.
m = (y2 -y1)/(x2 -x1)
m = (-1 -4)/(4 -(-1)) = -5/5 = -1
The slope of the line between the given points is -1.
Triangle: original side is 5 units long, copy side is 1 unit long
Scale = copy side/ original side = 1/5
Scale = 1/5
Second image:
Side of A is 6 units long
Side of B is 18 units long
Scale = B side / A side = 18/6 = 3
Scale = 3
