Determine whether the lines connecting each pair of points are parallel or perpendicular.
Line 1: (4, 3) and (5, 0)
Line 2: (1, 2) and (3, 4)
Its supposed to be 1/3 for both but i got 1/2 for the second line.

Best ResponseYou've already chosen the best response.1Line 1: (4, 3) and (5, 0) \(m_1 = \dfrac{0  3}{5  (4)} \) Line 2: (1, 2) and (3, 4) \(m_2 = \dfrac{4  (2)}{3  1} \)

Best ResponseYou've already chosen the best response.1@Lonnie2018 Use my last answer and find the two slopes.

Best ResponseYou've already chosen the best response.1also parallel lines have the same slope perpendicular lines have different slopes and we use this formula \[m_1 \times m_2=1\]
