Answer:
Perpendicular
Step-by-step explanation:
2x - y = -7
2x + 4y = 2
-y = -2x - 7
4y = -2x + 2
y = 2x + 7
y = -1/2x + 1/2
Cannot be:
Parallel because the slope would otherwise be the same.
Same line because the equation is not proportional
So, they are perpendicular because a perpendicular line would be a negative and a reciprocal of the current line
