which of the following lines is not parallel to y=2x+1
1)4x-2y=-4
2)2y-x=4
3)y-2x=6
4)2x-y=4

• math -

Y = 2x + 1
Slope = 2.
Parallel lines have equal slopes.

1.m = -A/B = -4/-2 = 2.

2. Standard Form: -x + 2y = 4.
m = -A/B = 1/2.

3. -2x + y = 6
m = 2/1 = 2.

Note: All lines with a slope of 2 ARE
parallel.

4. 2x - y = 4
m = -2/-1 = 2.
