An ordered pair \((x,y)\) is a solution of the linear equation \(Ax+By=C,\) if the equation is a true statement when the \(x\)- and \(y\)-values of the ordered pair are substituted into the equation.

The horizontal number line is called the x -axis, and the vertical number line is called the y-axis. These two number lines define a flat surface called a plane, and each point on this plane is associated with an ordered pair of real numbers (x,y). The first number is called the x-coordinate, and the second number is called the y-coordinate. The intersection is the origin: (0,0).

When an ...By rewriting y = −3 x + 5 y = −3 x + 5 as 3 x + y = 5 , 3 x + y = 5 , we can easily see that it is a linear equation in two variables because it is of the form A x + B y = C . A x + B y = C . When an equation is in the form A x + B y = C , A x + B y = C , we say it is in standard form of a linear equation.

It also explores angles in the Cartesian coordinate system, covering quadrants, angles in standard position, and coterminal angles. This foundation is critical for understanding Trigonometry's broader concepts, with practical examples and checkpoints to ensure comprehension.
