Find the slope of the lines pas

1. 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?
2. A quadrilateral has as vertices the points M(a,b), N(c,d), Q(c+d,e), P(a+d,e). Find the slope
   of each side.
3. C is the mid-point of AB, A if the point (-3,-2), and B is the point (2,8).
   What is the slope of BC?
4. 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?
