Question

Solve the following system of linear equations graphically. Also shade the region bounded by the lines and y – axis.  

x - y = 1 

2x + y = 8

Answer 1

The given equation is

x – y = 1

and 2x + y = 8

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

Table for x – y = 1 or y = x – 1

Here, the lines are intersecting at point C(3, 2).
