PreCalculus Chapter 1: Linear and Quadratic Functions Chapter 1: Linear and Quadratic Functions 1-1: Points and Lines System of Linear Equations: - two or more Linear equations on the same coordinate grid. Solution of a System of Linear Equations: - the intersecting point of two or more Linear equations - on the Cartesian Coordinate Grid, the solution contains two parts: the x-coordinate and the y-coordinate Line 1 Line 2 (can be expressed as an Ordered Pair). 9. 8. 7. Solution of the System of Linear Equations 6. 5. 4. 3. 2 Intersecting Point (x, y). 1. 0. -9 -8 -7 -6 -5 -4 -3 -2 -1. -1 0 1 2 3 4 5 6 7 8 9. -2. -3. -4. -5. -6. -7 We can find the solution of a system of Linear equation -8 graphing manually or using a graphing calculator. -9. Example 1: Find the solution of the following system of equations by graphing manually using x + 2y = 6. x y =3. 9. a. the slope and y-intercept form 8. Line 1 7 Line 2. For Line 1: For Line 2: 6. 5. x + 2y = 6 x y =3 4.
