Learning Objective
I can solve systems of linear equations using graphing, substitution, or elimination.
- 1
Linear equations take the form Y = MX + B and model many real-world relationships because they are neither too simple nor too complicated.
- 2
A system of linear equations is a set of equations where the variables are not raised to any exponent, and a solution to the system provides values for each variable that make all equations true.
- 3
A system of equations is considered consistent if it has at least one solution, and inconsistent if it has no solution.
