m1*m2=-1

anonymous · Answer

If the lines are parallel they will have the same slope.
If the lines are perpendicular, the slopes will be the opposite of each other
Use the slope formula to find the slopes use the points you have.
$$ m = \frac{Y_2-Y_1}{X_2 - X_1} $$

anonymous · Answer

slope of line a *slope of line b =-1 

then its perpendicular 
if slope of line a = slope of line b then its parallel ...

Also, when I said if they are perpendicular they will be opposite, I meant that the slope of one is the negative reciprocal of the other.
