look up khan academy they have algebra
videos i hope they have what you need
Eq 1 y = 2x + 3
Eq 2 y = 2x + 1
How can you determine these are parallel? Can you graph both equations? Is it possible the lines do intersect somewhere away from the coordinates you are plotting?

They are parallel because they both have the same coefficient of y, which is the slope. They will never intersect
