WORKBOOK
Examples:
1) Sketch the graph of the following lines which are passing through the points P and Q and
find their slopes If
i) P(1,0) and Q(4,2) ii) P(-2,-1) and Q(2,3)
Ex: Find the slope of line PQ which is passing through the points P and Q and sketch its graph
if
i) P(1,3) and Q(4,3) ii) P(-2,3) and Q(-2,1)
NOTE: Remember, three points are said to be collinear if they are on the same line.
Ex: Find the value of k, if A(1,3) , B(3,-2) and C(k+2, k-4) are collinear.
