Description

"Linear Equations and Functions of Two Variables" PPT courseware for systems of linear equations of two variables

Think about it:

1. How many solutions are there to the equation x+y=5?

2. Are the points (0,5), (5,0), (2,3) on the graph of the linear function y=-x+5?

3. Pick any point on the graph of the linear function y=-x+5, do its coordinates fit the equation x+y=5?

4. Is the image composed of all points with the solution of the equation x+y=5 as coordinates the same as the image of the linear function y=-x+5?

Graphical relationship between linear equations and linear functions

1. The points whose coordinates are the solution of the linear equation of two variables are all on the corresponding function graph;

2. The coordinates of the points on the graph of a linear function are suitable for the corresponding linear equation of two variables.

The relationship between the system of equations and the corresponding two straight lines

1. The solution to the system of equations is the coordinates of the intersection of the corresponding two straight lines.

2. The coordinates of the intersection of two straight lines are the solutions to the corresponding system of equations.
