Question

Which answer describes the graph of the system of equations?
y=4-x
2y=8-2x
The point of intersection is (0, 4).
The point of intersection is (4, 0).
The lines are parallel.
The lines coincide.

Answer 1

The lines coincide.

Reason: 2y = 8 − 2x simplifies to y = 4 − x, which is the same equation as the first, so every point on one line lies on the other.
