Draw and name: Line passing through R.

Find the equation of the line containing the points (1,2) and (1,-2)

Find the slope of a line, which passes through the origin, and the mid-point of the line segment joining the points P (0,- 4) and B (8,0).

P is a point equidistant from two lines l and m intersecting at point A (see figure). Show that the line AP bisects the angle between them.
