Answer:
A'(4,-5), B'(1,-6), C'(2,-3)
Step-by-step explanation:
Reflect across the line y = -1 to get these points. You can count how many points it takes to get to that line and then add the same amount of points to the other side.
b
3.87298334621
p=3h + 3u subtract 3u from both sides
p-3u=3h now divide both sides by 3
h = p/3 - u
