A line contains the points (0, 2) and (1,3). Another line graphed in the same coordinate plane contains the points (3, 1) and (2,0).
Based on the slope of these lines, are they parallel, perpendicular or neither?

(0,2),(1,3).
(3,1),(2,0).
m1 = (3(2)) / (10) = 5/1 = 5.
m2 = (0(1)) / (23) = 1/5 = 1/5.
mi and m2 are negative reciprocals of each other.Therefore, the lines are
perpendicular.
