How do you determine whether the lines for each pair of equations 3x+2y=-5 y=-2/3x+6 are parallel, perpendicular, or neither?
The lines are not parallell, nor are they perpendicular.
First, we get the two linear equations into
If the lines were parallell, they would have the same
If the two lines are perpendicular, their
This is almost the negative reciprocal, but we're off by a minus sign, so the lines are not perpendicular.
Neither parallel nor perpendicular
the other equation is,
Now,slope of both the equations are not equal,so they are not parallel lines.
Again,product of their slope is
But,for two lines to be perpendicular, product of their slope has to be
So,they are not perpendicular as well.
