i dont understand equations of parallel and perpendicular lines here's one of my teachers examples y=2x+4 (-2,1)

1 answer:

Parallel lines will never touch each other while perpendicular forms like an X shape. The slope for the parallel is the same while the perpendicular is a negative reciprocal. (Ex for negative reciprocal. 2/4=4/2)

Evaluate y^0. Please show working out. Thank you

So what would happen is that y is always the same, so if y is 2, then it will always be 2, however x does change. this is called a zero or no slope. Happy Valentines!
