C. y−4x=6y+4x=−6
D. y=−3x+1y+4x=x−1

Answer 1

Which pair of lines are parallel? Select all that apply.
===============
Do you mean?

A. y=3−2x
y=2x−3
B. y=2x−1
y−2x=8
C. y−4x=6
y+4x=−6
D. y=−3x+1
y+4x=x−1

if so then write as

A.
y=-2x + 3 slope = -2
y=+2x−3 slope = +2

B.
y=2x−1 slope = +2
y=2x+8 slope = +2

C.
y=4 x +6 slope = 4
y=-4x - 6 slope = -4

D.
y=−3x+1 slope = -3
y= -3x−1 slope = -3
