SOLUTION: Line A goes through the points (0,6) and (3,8), Line B goes through the points (0,-2) and (2,-5). Are lines A and B parallel, perpendicular, or neither parallel nor perpendicular?

Question 357041: Line A goes through the points (0,6) and (3,8), Line B goes through the points (0,-2) and (2,-5). Are lines A and B parallel, perpendicular, or neither parallel nor perpendicular? Express with the slopes of the two lines.

Find the slopes of the 2 lines.
slope m = diffy/diffx
m1 = (8-6)/(3-0) = 2/3
----------------------
Find the other slope the same way.
If the slopes are the same (2/3) they're parallel.
If the 2nd slope is the negative inverse (-3/2) they're perpendicular.
If neither, they're neither.
