Fig. 11 shows the line through the points \(\mathrm { A } ( - 1,3 )\) and \(\mathrm { B } ( 5,1 )\).
- Find the equation of the line through \(\mathbf { A }\) and \(\mathbf { B }\).
- Show that the area of the triangle bounded by the axes and the line through A and B is \(\frac { 32 } { 3 }\) square units.
- Show that the equation of the perpendicular bisector of AB is \(y = 3 x - 4\).
- A circle passing through A and B has its centre on the line \(x = 3\). Find the centre of the circle and hence find the radius and equation of the circle.
