we know that
If two lines are parallel, then their slopes are the same
m1=m2
and the y-intercept is unequal
If two lines are perpendicular, then the product of their slopes is equal to -1
m1*m2=-1 or m1=-1/m2
therefore
<u>the answer is</u>
Two non vertical lines have slopes m1 and m2, respectively. The lines are parallel if m1=m2 and the y-intercept are unequal; the lines are perpendicular if m1*m2=-1 or m1=-1/m2.
