Question #73525

Answer 1

Linear.

Explanation:

graph{2/5x [-10, 10, -5, 5]}

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.

Answer 2

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

Explanation:

`"if you mean " y=2/(5x)" then y is a rational function"`
`"and is non-linear"`
