Line BC has an equation of a line y = 2x + 3, and line EF has an equation of a line y = −3x + 4. These two equations represent

parallel lines because the slopes of the lines are the same

perpendicular lines because the product of the slopes is −1

the same line

lines that are neither parallel nor perpendicular

@melody16 (i saw you were good at geo) im thinking it is D because they cant be parallel due to the negative 3x and the positive 2x. also not the same due to the different starting points. I'm stuck between B and D but i think D

anonymous · Answer

I think youre right.

anonymous · Answer

is it possible that it is B?

anonymous · Answer

no because in order for it to be perpendicular it has to have opposite reciprocals. so if one line's slope is 2 then the opposite reciprocal is -1/2 which would make that line to be the perpendicular one.

understand?

Yes. Thank you :) i just wanted to double check.
