which of the following lines is not parallel to y=2x+1
1)4x2y=4
2)2yx=4
3)y2x=6
4)2xy=4

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.
