  1. Slope (m) of the intersecting lines through the points (x1, y1) and x2, y2) is given by \(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{y_{1}-y_{2}}{x_{1}-x_{2}}\); where x1 ≠ x2
  2. An acute angle θ between lines L1 and L2 with slopes m1 and m2 is given by \(tan\:\theta =\left | \frac{m_{2}-m_{1}}{1+m_{1}.m_{2}} \right |\); 1 + m1.m2 ≠ 0.
  3. Equation of the line passing through the points (x1, y1) and (x2, y2) is given by: \(y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1})\)
  4. Equation of the line making a and b intercepts on the x- and y-axis respectively is: \(\frac{x}{a}+\frac{y}{b}=1\)
  5. The perpendicular distance d of a line Ax + By + C = 0 from a point (x1, y1) is: \(d=\frac{\left | Ax_{1}+By_{1}+C \right |}{\sqrt{A^2+B^2}}\)
  6. The distance between the two parallel lines Ax + By + C1 and Ax + By + C2 is given by: d=\(\frac{\left | C_{1}-C_{2} \right |}{\sqrt{A^2+B^2}}\)
