Locate the points P (3, 4), Q (1, 0), R (0, 4), S (4, 1) on a graph sheet and write the coordinates of the point of intersection of line segments PQ and RS.

Graph1 : plotting the points

Graph 2 : drawing the lines and finding their intersection

From the second graph , we see that N is the point of intersection of PQ and RS.

Its co-ordinates from the graph can be seen are N(2.1,2.4).
