Coordinate system is a pair of perpendicular coordinate lines. Lines are called coordinate axes. Also the point where both interest is origin. Therefore point (x,y) is location on XY-plane. Graph in XY-Plane

Linear functions-Lecture 12
Two variable linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. Linear functions
Graphic linear system-Lecture-11
Linear system can be solve by graphing. A linear system that has exactly one solution. Hence it intersect at x- axis once. Graphing linear system
Algebraic Absolute Inequality-Lecture-8
The solution to an absolute-value inequality is to be intervals. Also we can say solution of inequality is range of values. Hence on graph it represent by area . Algebraic absolute inequality
Heart of Algebra
Algebra is a branch of mathematics dealing with symbols and the rules. Therefore we can say equation is relationships between variables. Algebra
System of equation-Lecture-7
A “system” of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables. System of equation

SAT Math Test focus on the mastery of linear equations, systems of linear equations, and linear functions. Hence it is heart algebra. Heart of Algebra
Algebraic Inequality-Lecture-6
Inequalities are used to compare the relative size of values. In the two types of strict inequalities, aa is not equal to bb. To compare the size of the values, there are two types of relations: The notation a<ba<b means that aa is less than bb. The notation a>ba>b means that aa is greater than […]
