Disagree because if b is 1, the the lines will share the same coordinates points as well as lies on the other
find the slopes
paralell ines have same slope
y=mx+b
m=slope
y=2x+b
2=slope
find slope between the other points
slope betwen (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(2,5) and (-1,-1)
slope=(-1-5)/(-1-2)=-6/-3=2
2=2
the slope are equal so threfor I agree that they will be paralell
