When the linear inequality ax + B of one variable is greater than 0 or ax + B is less than 0 and is a linear function y = ax + B (a is not equal to 0), it can be regarded as the --- of the linear function y = ax + B

One variable linear inequality ax + b greater than 0 or ax + b less than 0 is a linear function y = ax + B (a is not equal to 0)
It can be seen that when the [function value is greater than 0 or less than 0] of a function y = ax + B,
Find the corresponding value range of the independent variable
