Hi, i hope this helps! The coordinates are (6,6). I figured this out by plotting the given points and remembering that a rectangle has parallel sides and right angles :))

➷ Substitute the value for 'x' in every time you see x
1) y = -2(-2) + 6
y = 10
2) y = -2(0) + 6
y = 6
3) y = -2(2) + 6
y = 2
4) y = -2(4) + 6
y = -2
5) y = -2(6) + 6
y = -6

The little lines on each side of the rhombus mean that all the sides are the same length.
We can set line LM and MN equal to solve for X, then we can solve the length of a side.
3x-3 = x+7
Add 3 to each side:
3x = x +10
Subtract x from each side:
2x = 10
Divide both sides by 2:
x = 10/2
x = 5
Now we have the value for x, replace x in one of the side formulas:
x +7 = 5+7 = 12
Each side = 12 units.
The perimeter would be 12 + 12 + 12 + 12 = 48 units.
6x+6y=1500 like this i think
I think the first one is C
