Question:
Graphical representation of linear equations
Solve the questions on graphical representation of linear equations. Show all of your work and plot the graphs using the EZGraph tool.
1. Plot the graph of the equations 2x - 3y = 5 and 4x - 6y = 21 and interpret the result.
2. Plot the graph of the equations 4x - 6y = 12 and x - 5y = 10 and interpret the result.
3. Plot the graph of the equations 8x - 4y = 12 and -4x + 2y = -6 and interpret the result.
Did the graphs but still don't seem like right answers. Think I am doing the solutions wrong. Not sure if I should use substitution, or elimination method.
