Answer:
y =
- 8
y = -
+ 3
y =
- 8
y = 
Step-by-step explanation:
To know the pairs that are perpendicular lines, we need to understand what makes a line perpendicular to another.
Perpendicular lines generally have slopes;
m and
So, any of the pairs with a negative inverse value of slope will be perpendicular.
y =
- 8 slope = 
y =
slope = 
We see they are negative inverses
y =
- 8 slope = 
y =
slope = 
These are also negative inverses.
