Discussion:
Solve the following questions on graphical representation of linear equations. Your response should include the graphs for each of these questions.
1. Plot the graph of the equations 3x - 2y = -6 and 4x + 2y = -11 and interpret the result.
2. Plot the graph of the equations 3x - 5y = 14 and -6x + 10y = 9 and interpret the result.
3. Determine graphically the vertices of the triangle, the equation of whose sides are given as y = x; x = 0; 4x + 2y = 12. Interpret the result.
