Step-by-step explanation:

Parallel lines have the same slope.

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

We have the equation of a line c:

Therefore the equation of a line d parallel to a line c is:

The lines c and d are different. Therefore y-intercepts must be different

(b ≠ -5).
