The relationship is as follows:

1, k＞0, b＞0, passing through the 1, 2, and 3 quadrants.

2, k>0, b

3, k

4, k0, passing through quadrants 1, 2, and 4.

A linear function is a type of function, generally in the form of y=kx+b (k, b are constants, k≠0), where x is the independent variable and y is the dependent variable. In particular, when b=0, y=kx (k is a constant, k≠0), and y is called a proportional function of x.

Linear functions and their graphs are an important content of junior high school algebra, the cornerstone of high school analytic geometry, and a key test content in the high school entrance examination.

There are three ways to represent a linear function, as follows:

1. Analytical expression method:

The method of expressing a function using an expression containing the independent variable x is called the analytic expression method.

2. List method:

The method of listing the function values ​​y corresponding to a series of x values ​​into a table to express the functional relationship is called the list method.

3. Image method:

The method of using images to represent functional relationships is called the image method.

Functional properties of linear functions.

1. The change value of y is directly proportional to the corresponding change value of x, and the ratio is k.

That is: y=kx+b (k≠0) (k is not equal to 0, and k and b are constants).

2. When x=0, b is the intersection point of the function on the y-axis, and the coordinates are (0, b).

When y=0, the intersection coordinate of the function graph on the x-axis is (-b/k, 0).

3. k is the slope of the linear function y=kx+b, k=tanθ (the angle θ is the angle between the graph of the linear function and the positive direction of the x-axis, θ≠90°).
