Determinant for matrix 2x2:
- Determiant for matrix 3x3:
Equivalent system: A system of equations having the same solution set as another system.
Graph of an equation in two variables: All the points that may be graph from the solution set of the equation.
Graph of a function: The solution set graphed for the function in the given domain.
Graph of a number: The location of a point paired with a number in the number line.
Graph of an ordered pair: The location in the coordinate plane associated with an ordered pair of real numbers.
Linear equation: Any equation with all exponents = 1 regardless of the form the equation is represented.
Linear equation in two variables: All equivalent equations to the one in the form of ax + by = c, where a, b, and c are in the set of the real numbers and a and b can't be zero at the same time. The graph is a straight line.
Linear function: A function of the form: f(x) = mx + b.
Matrix: Rectangular arrangement of numbers in rows and columns that uses large brackets in order to define the matrix. A matrix size is defined by number of rows and number of columns.
Ordered pair: In a coordinate plane is the location of a point.
Slope of a line:The measure of how steep a line is. The change in y (rise) divided by the change in x (run). Slope = m
Slope-intercept form of an equation: The equation of a line in the form y = mx + b, where m represents the slope, and be represents the y-intercept.
Solution of an equation in two variables: Any ordered pair of real numbers that makes the sentence true.
Solution of a system of two equations in two variables: Ordered pair that when replaced in the equations produces a true statement for both equations.
Solve a system of two equations in x and y: Finding all ordered pairs (x,y) which make both equations in the system true.
Standard form of a linear equation: ax + by = c, where a, b, and c are integers and a and b are not both zero.
