Guided Notes

3 key concepts

  • 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.
