Parallel equations do not share the same y intercept. The equation is independent and inconsistent. No solution
Lines that intercept are Independent and consistenet with only one solution.

When you write a line's equation in slope-intercept form, y=mx+b, the slope is m and the y-intercept is b. Parallel lines have the same slope. If they have both the same slope and same y-intercept, then they're the same line.
Usually though, the problem is finding a ine that's parallel to a given line and passes through a given point. In that case you'd find "b" by plugging the slope and point coordinates into y=mx+b, solving this for b, and putting this value along with the slope into y=mx+b.

Parallel lines have the same slope (m) and like you said, they already gave you the y-intercept (b).

Perhaps you need to include the exact question because as far as I know, if they are parallel, they would not have the same y-intercept unless it is the same equation.

if the lines are parallel they should have the same slope
so, M1=M2 or in laymans terms slope of first equals the slope of second.

the slopes must be equal i.e.
y=2x+5
y=2x-5
5x+3y=10
5x+3y=-3
