  2. 1.5 Linear Equations

    Slide 2 - 1.5 Linear Equations

    • What are linear equations?
    • Linear equations are equations that have at least one variable and an equals sign. The highest power of the variable must by 1.
    • The highest power being 1 makes it linear, and the equals sign makes it an equation.
    • Linear Equations: Not Linear Equations:

    Slide 3 - 1.5 Linear Equations

    • How do we solve them?
    • We use our algebra skills to get the variable on one side of the equals sign, and everything else on the other.
    • The way that we do this is by reversing the operations that are in use.
