Question

Line WX contains (−1, 2) and (4, 12) Line YZ contains points (5, 8) and (−2, −6). Lines WX and YZ are

Answer 1

perpendicular, because the slopes are the same

parallel, because the product of the slopes is −1

perpendicular, because the product of the slopes is −1

parallel, because the slopes are the same

Answer 2

y-12=2(x-4) = wx

Answer 3

yz = y-8=2(x-5)

Answer 4

just use y-y1 = m (x-x1) in which m means gradient

Answer 5

@CaseyCarns
How to find the slope of a line?

Answer 6

I know it's either B or C

Answer 7

of course they are parallel because they have the same gradient (slope)

Answer 8

So it's C

Answer 9

product of the slopes becomes -1 if only they are perpendicular

Answer 10

answer is D
