Using slope concept, show the points P(3,0),Q(6,-2) and
R(-3,4) are colinear.

Show that the points P(2,6),Q(1,2)and R(3,10) are collinear.

Show that points P(5,6) , Q (4,5) and R = (3,4) are collinear .

6.Show that the points P(-frac{3}{2},3),Q(6,-2), and R(-3,4) are collinear.

(A) Complete any one out of two activities : Complete the following activity to show the points P(3,0) Q (6,-2) and R (-3,4) are collinear . Let P( 3,0) = (x_(1) ,y_(1)) Q (6,-2)= (x_(2),y_(2)) R (-3,4) = (x_(3) , y_(3)) slope of a line PQ = (y_(2)-square)/(x_(2) -x_(1)) = (-2-0)/(6-3)= square " " ...(1) slope of line QR = (y_(3) -y_(2))/(x_(3)-x_(2))= (square -(-2))/(-3-6) = (4+2)/(-9) = 6/(-9) = square " " ... (2) :. from (1) and (2) the slopes of lines PQ and QR are square and point square is the :. points P,Q and R are collinear .
