What is the slope of the line parallel to the line passing through the points (5, -1) and (4, -4)?

$$\eqalign{ & {m_1}\left( {{\text{slope}}} \right) = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}} \cr & \Rightarrow \frac{{ - 4 - \left( { - 1} \right)}}{{4 - 5}} \cr & \Rightarrow \frac{{ - 3}}{{ - 1}} = \left( 3 \right) \cr & \therefore {m_1} = {m_2}\left( {{\text{In parallel condition}}} \right) \cr & \therefore {m_2} = 3 \cr} $$
