Answer:
Step-by-step explanation:
<u>Step 1 :</u>-
<u>Perpendicular condition :-</u>
<u>Step 1:-</u>
Two non-vertical lines are perpendicular to each other if and only if their slopes are negative reciprocals of each other.
<u>Step 2:-</u>
The given points are (-8,k) and (-4,-8)
finding slope of the first line is
using formula
=
finding slope of the second line is
using formula
=
<u>Step 3:</u>-
using perpendicular condition
The two lines are perpendicular and their slopes are
simplification,we get solution is
<u>Final answer is </u>
