Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question
<h3>

</h3>
Comparing it with the general equation above
Slope / m = 1/3
Since the lines are perpendicular to each other the slope of the other line is the negative inverse of the original line
That's
Slope of perpendicular line = - 3
Equation of the line using point (-4 , 1) and slope - 3 is
<h3>

</h3>
We have the final answer as
<h3>y = - 3x - 11</h3>
Hope this helps you
