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.
