Answer:
Explanation:
first, to find if they are perpendicular, we would have to determine their slopes.
y=-2x-1, we know that the slope is -2 (due to y=mx+b, where m is the slope)
y=-2x+6, we also know that the slope is -2.
since the slope is equal, it would be parallel.
However, if the slopes were negative reciprocals, (e.g. 1/2 & -2) they would be perpendicular.
If the slopes were neither negative reciprocals or equal, it would be neither.
