Problem of System of Linear Equation Two Variables with Graph Method
Learning objectives
1. Identify the linear equation of two variables
2. Solve problems related to a systemof linear equations of two variables
3. Solve the system of linear equations of two variables using the graph method
Example:
Determine the solution set for the following system of linear equations using the graphical method
3x + 4y = 12
2x + 4y = 8
From the graph, we get
The intersection or solution set of the equatuions is (4,0)
Exercise
