Which statement is true about the graphs of the two lines y=-8x-5/4 and y=1/8x+4/5

Answer:
First option
The lines are perpendicular to each other because -8 and 1/8 are opposite reciprocals of each other
Step-by-step explanation:
y = -8x - 5/4; slope = -8
y = 1/8 x + 4/5; slope = 1/8
Perpendicular lines, slope is opposite and reciprocal.
So both lines are perpendicular to each other because -8 and 1/8 are opposite reciprocals of each other
