Analytic Geometry Formula:

Mid point formula: $\left ( \frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2} \right )$

The distance formula is used to find the distance between two points A (x1 ; y1) and B (x2; y2)

AB = $\sqrt{\left ( X_{2}-X_{1} \right )^{2}+\left ( Y_{2}-Y_{1} \right )^{2}}$

The gradient of the line = $\frac{Y_{2}-Y_{1}}{X_{2}-X_{1}}$ 

The equation of a straight line is given by y = mx + c

The equation of the perpendicular bisector  = y – y1 = m(x – x1)
