Exercise 2.1
1.Find the slope of each line which contains each pair of points listed below.
(a) (0,0) and (8,4) (b) (10,5) and (6,78) (c) (2,-2) and (4,2)
(d) (0,3) and (-2,3) (e) (-2,0) and (0,6) (f) (15,6) and (-2,23)
(g) (-5,7) and (3,8) (h) (63,49) and (-7,9) (i) (5/2 ,4/3 ) and (-13/2 ,16/3 )
(j) (2a,3b) and (-a,b) (k) (5√2 ,6√3 ) and (√8, √12) (l) (0,n) and (n,0)
Find the slope of theS(3,2), T(4,6), V(2,8). Find the slope of
each side.
- 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? - 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. - 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? - 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?
