Consider the line x+2y=6.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Slope of a perpendicular line:

Slope of a parallel line:

Respuesta :

X+2y=6 = y=-1/2x+3
Slope=-1/2
Perpendicular is opposite so slope is2/1 or just 2
Parallel slope is the same so also -1/2
