line through points:
(-2,-6) and
(0,0) m = -6/-2 = 3
Lines parallel to this line will have slope = 3
Lines perpendicular to this line will have slope = (-1/3)

Slope:
m=%28-6-0%29%2F%28-2-0%29=6%2F2=3
Parallel line would have identical slope.
m%5Bpar%5D=3
Perpendicular line would have slope that is negative reciprocal.\
m%5Bperp%5D=-1%2F3
