Hey Insignia21,

A good piece of information to know here is that if 2 lines are parallel, they will have the

__same__ slope, and if they are perpendicular, the slopes will be

__negative reciprocals of one another__.That said, we can see clearly the the slope of

is

. We know this from knowing the formula for a straight line

where

So we know that for

to be parallel, it must have a slope of

, and if it is perpendicular, it must have a slope of

.

Now we must solve the first equation for y and find the slope, and then compare it to the above.
