first recall that is the slope-intercept form of the linear equation where is a slope and is y-intercept
the graph of differ from that of in y-intercept (the point where the line crosses the y-axis)
this one has y-intercept , and this one has y-intercept ; means that the graph of intercept y-axis units in higher point then the graph of
but, these two graphs have same slope which is and that is telling us that lines are
here is one example:
let first equation => the slope is and the y-intercept is point (0, 10),
let second equation => the slope is and the y-intercept is point (0, 6),
now, graph them to see that these lines are parallel, just their the y-intercept point is different
