    Study Notes

    Linear Functions

    • A linear function can be represented as a straight line.

    Quadratic Equations

    • The end behavior of a graph of a quadratic equation with a positive leading coefficient is that the graph opens upward.
    • A quadratic equation can be represented by a graph that forms a U-shaped curve.

    Slope

    • The slope of a line parallel to the line with equation $3x - 4y = 8$ is $\frac{3}{4}$.

    Systems of Equations

    • If there are no solutions in a system of equations, it means that the lines are parallel and do not intersect.
    • In a system of 3 equations and 3 unknowns, there are three possible solutions: one unique solution, no solution, or infinitely many solutions.

    Graph Characteristics

    • A graph that does not have any breaks or holes represents a continuous function.

    Y-Intercept

    • The y-intercept of the line with equation $2x - 3y = 6$ is 2.
