# Use a single graph paper and draw the graph of the following equations. Obtain the vertices of the triangle so formed:2y – x = 85y – x = 14y – 2x = 1

The given equation is

– x + 2y = 8

– x + 5y = 14

and – 2x + y = 1

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