The given equation is 3x – 5y = 19 and 3y – 7x + 1 = 0 or 7x – 3y = 1
Now, let us find atleast two solutions of each of the above equations, as shown in the following tables.
From the graph, it is clear that lines represented by the equations 3x – 5y = 19 and 7x – 3y – 1 = 0 are intersecting at a point C i.e. ( – 2, – 5).
Yes, point (4,9) lie on 3y – 7x + 1 = 0.
