Answer:
W is the point of intersection of the lines 'a' and 'b'.
Step-by-step explanation:
Three points lying on line 'b' are points Y, Z and W.
Similarly, three points on line 'a' are points V, X and W.
Common point lying on both the lines 'a' and 'b' is W.
Therefore, point of intersection of the lines 'a' and 'b' is W.
