Answer:
x= -3, y=-6
Step-by-step explanation:
In the equation -5x-y=21, substitute y for 6+4x:
-5x- (6+4x) = 21
^^Solve for x.
X should come out to -3. To find y, plug -3 into either equation (-5x-y=21 or y=6+4x) and y should equal -6.

Answer:
c
Step-by-step explanation:


add -x to both sides

multiply both sides by -1/2


the equations don't have the same slope so they aren't parallel
The solpes product doesn't equal -1 so they aren't perpendicular

Answer:
Either of ...
- (x, y) ⇒ (-x, -y)
- Rotation 180° about the origin
Step-by-step explanation:
There are at least two ways to express the transformation that maps each coordinate to its opposite.
1. reflection across the origin: (x, y) ⇒ (-x,-y)
2. rotation 180° (either direction) about the origin.
Take your pick.
