    Study Notes

    Conditional Equation

    • True for certain values of the variable but not for others.

    Contradiction Equation

    • An equation with no solution, exemplified by x = x + 1.

    Identity Equation

    • An equation that holds true for any value assigned to the variable.

    Union Symbol

    • Represented by "U" and indicates the use of "or."

    Intersection Symbol

    • Denoted by an upside-down "U" and signifies the use of "and."

    Slope-Intercept Formula

    • The formula to find the equation of a line: y = mx + b, where m is the slope and b is the y-intercept.

    Slope Formula

    • Calculated as (y2 - y1) / (x2 - x1) to determine the steepness of a line.

    Parallel Lines

    • To identify parallel lines in an equation, they must have the same slope but different y-intercepts.

    Perpendicular Lines

    • Lines are perpendicular if their slopes (m) are opposite reciprocals of one another.

    Finding the X-Intercept

    • To find the x-intercept of a function, set y to 0 and solve for x.

    Finding the Y-Intercept

    • To find the y-intercept, set x to 0 and solve for y.

    Consistent System

    • A system of equations or inequalities with at least one solution.

    Inconsistent System

    • A system characterized by having no solutions at all.

    Dependent System

    • A system of equations with infinitely many solutions due to matching lines.

    Independent System

    • A system of equations that results in exactly one unique solution.
