Answer:
-y=-x
The problem:
y=x then -y=?
Step-by-step explanation:
If y=x, then -y=-x.
Just like if u=9, then -u=-9.
Or, if -m=8, then m=-8.

b = base length (of triangle)
h = height of triangle
s = side length of triangle
l = length of rectangle
The range is the y-coordinate of the points
Hence, range = {-2, 2, -4, 2} = {-4, -2, 2)
2 cannot be written twice.
