Question

Two lines in a coordinate plane have no points of intersection. Which pair could be the equations of the lines? A. 3x-2y=6, 6x-4y=12 B.7x+y=10,3x-2y=-3 C.-x+y=5,3x+4y=2 D.-x+y=1,3x+4y=8

Answer 1

A.

Explanation:

if to re-write all the equations:

A. y=3/2 x-3; y=3/2 x-3; B. y=-7x+10; y=3/2 x+3/2; C. y=x+5; y=-3/4 x+2; D. y=x+1; y= -3/4 x+8.

According to the re-written view the correct answer is 'A'.
