x = negative 1 is a vertical straight line parallel to the y axis at x = -1 ; its slope is infinite
-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
They are parallel lines
y-2x=3 -y -y -2x=3-y -3 -3 -2x-3=-y /-1 /-1 2x+3=y y=2x and y=2x+3 have the same slope of 2, so they are parallel. Hope this helps! ;D
2x-4y = 16 -4y = -2x+16 y = 1/2x-4 Any equation that has a slope of 1/2 but a different intercept of -4.

If you want to graph parallel lines, they need to have the same slope (Ex. 2x+2 and 2x+3)- parallel lines cannot have the same y-intercept because the two line would be the same. Perpendicular lines slopes need have to be opposite reciprocals (Ex. -2x+4 and +1/2x+3)- perpendicular lines can have the same y-intercepts, it doesn't make a difference.
No they are parallel.

5y = 2x - 5; y = (2/5)x - 1 Since two non-vertical line are parallel if they have the same slope, then 5y = 2x - 5 is parallel to any line with equation y = (2/5)x + c
If you mean: y = 2x-4 and (1, 5) then the parallel equation is y = 2x+3
As stated these are not lines, but just a collection of algebraic terms. If we change them to y=2x and y=2x-1, then on a graph of y versus x, these are parallel lines separated by vertical distance of 1.

As for example the perpendicular equation to line y = 2x+6 could be y = -1/2x+6 because the negative reciprocal of 2x is -1/2x
Without an equality sign the given expression can't be considered to be a straight line equation. But if you mean: y = 2x-1 then the parallel equation is y = 2x+5
