1) Perpendicular to </span>

In order for lines to be
perpendicular, their slopes must be
negative reciprocals.Example of slopes with negative reciprocals: 5 and

First,
rearrange the equation into
slope y-intercept form:




The
slope of the equation is: \frac{1}{5}
The
negative reciprocal formula:

Solve for the negative reciprocal:
Divide both sides by





The slope of the new line is:
-5
2) Passes through (-5,-2)
Create an equation with the slope discovered in slope y-intercept form.

Input the point the line passes through.

Solve for b (the y-intercept).

Multiply.

Add -25 to both sides.


The y-intercept is equal to
-27
The Equation of the line is:

I hope this helped!
