Question 1126444: Lines l1 and l2 past through the given points. Determine if l1 and l2 are parallel, perpendicular, or neither.
l1: (1,3) and (0,0)
l2: (0,7) and (-2,1)
How would you solve in order to compare? Thank you.

Use the slope formula to find the slope of the line through (1,3) and (0,0)
(x1,y1) = (1,3) and (x2,y2) = (0,0)
The slope of line L1 is 3
--------------------------------------------------------
Repeat these steps to find the slope of line L2
(x1,y1) = (0,7) and (x2,y2) = (-2,1)
The slope of line L1 is also 3
--------------------------------------------------------
Both lines L1 and L2 have the same slope 3, so the two lines are parallel as this graph shows below
These two parallel lines will never intersect.
