  1. The vertices of a triangle ate the points A(-2,3), B( 5,-4) and C(1,8). Find the slope of each
    side and also the slope of median.
  2. The vertices of parallelogram are the points R(1,4), S(3,2), T(4,6), V(2,8). Find the slope of
    each side.
  3. Determine the slope of each side of the quadrilateral whose vertices are A(5,6), B(13,6),
    C(11,2). Can you tell what kind of quadrilateral it is?
  4. A quadr BC?
  5. Given the points D(-4,6), E(1,1), F(4,6), find the slopes of DE and EF. Are D,E and F
    collinear ? Why?
