Linear Graphs

Linear functions are those whose graph is a straight line.

A linear function has the following form

#y = f(x) = a + bx#

A linear function has one independent variable and one dependent variable. The independent variable is #x# and the dependent variable is #y#.

#a# is the constant term or the y intercept. It is the value of the dependent variable when x = 0.

#b# is the coefficient of the independent variable. It is also known as the slope and gives the rate of change of the dependent variable.

#"if " y=2/(5x)" then non-linear"#

Explanation:

#"if you mean " y=2/(5x)" then y is a rational function"#
