Question

Segment AB is on the line y − 4 = −5(x − 1), and segment CD is on the line y − 4 = 1/5(x − 5). Which statement proves the relationship of segments AB and CD?

They are perpendicular because they have slopes that are opposite reciprocals of 5 and -1/5.
They are perpendicular because they have slopes that are opposite reciprocals of −5 and 1/5.
They are parallel because they have the same slope of 5.
They are parallel because they have the same slope of -1/5.

Answer 1

can you give us a graph or does it not have one?

Answer 2

it doesnt have one

Answer 3

okay

Answer 4

hm

Answer 5

what would be your best guess?

Answer 6

I havent a clue

Answer 7

okay let me see

Answer 8

hints:
The slope of \(y-y_1 = m(x-x_1)\) is \(m\)

Perpendicular lines have their slopes always multiply to -1, assuming neither line is vertical.
