The path of a whe

The given equation is

x + 2y – 4 = 0

and

2x + 4y – 12 = 0

Now, let us find atleast two solutions of each of the above equations, as shown in the following tables.

Table for x + 2y – 4 = 0

Now, table for 2x + 4y – 12 = 0

From the graph, it is clear that lines represented by the equations x + 2y – 4 = 0 and 2x + 4y – 12 = 0 are parallel.
