Question

Which equation represents a line which is parallel to the line Y= 1/2 X +3 1. y-2x=-5 2. 2x+y=-6 3. x-2y=2 4. x+2y=4

Answer 1

x-2y=2.

Explanation:

1) if to re-write all the given equations of the lines, then

y=2x-5; y=-2x-6; y=1/2x-1; y= -1/2x+4.

2) y=1/2x-1 only is parallel to the given y=1/2x+3.
