You can put this solution on YOUR website!
First I want to clarify that you understand your own question
Each equation represents a straight line and you want to
know if these two line intersect ar right angles, are parallel
or intersect at some other angle
First, put both equations in the slope-intersect form which
is where is the slope
Subtract from both sides
The other equation:
Add to both sides
Divide both sides by
The slopes are perpendicular if they are related like this:
where and
The lines are perpendicular because
