Question 929193: 13. Determine whether the graphs of 2y-8x=16 and y=1/4x-5 are parallel, perpendicular, or neither. explain
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! 2y - 8x = 16
y = 1/4x - 5
---
2y = 8x + 16
y = 1/4x - 5
---
y = 4x + 4
y = 1/4x - 5
---
the slopes of the two lines (4 and 1/4), are neither equal nor negative reciprocals, therefore the lines are neither parallel nor perpendicular
