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.
And from this we can see that the slope of
is which when compared above is not the same or the negative reciprocal of the second equation. Therefore the 2 lines are neither parallel or perpendicular.
Does this help?
